DHH’s new way of writing code
3001 segments
I feel that you very much value software
engineering as a craft
>> hugely. I mean I think aesthetics is
truth. When something is beautiful, it's
likely to be correct. I think this is
true in mathematics. This is true in
physics. This is true in a lot of
different domains.
>> I wonder if there's a part of AI about
the impact of doing work that we would
have not done before.
>> The number of projects we have tackled
internally that we would never even have
contemplated starting on or Legion.
Jeremy, one of our most agent
accelerated people, went like, "We're
going to do P1. We're going to optimize
P1." Literally the fastest 1% of
requests, we're going to make them even
faster. There's a bit of tension right
now is that most of the people I find
who are all in, they're working harder
than they ever have. And I've seen that
with myself now, too. When you can be
this effective and impactful on an hour
of supervision of these agents, it's
really intoxicating. And I need to go,
do you know what? This is not like a
limited sale. on Lex Freriedman's
podcast. You were still rightfully so
very skeptical of AI.
>> This is a nuance point and maybe it's
self- serving, but I don't actually
think my opinions have changed. What
have changed is
how has the creator of Ruby on Rails
changed how he builds software now with
AI agents? David Hayam Hire Hansen often
referred to as DHH created Ruby on Rails
Omachi and is a co-founder of 37
signals. He bashed capabilities of AI
coding tools on Lex Friezen's podcast 6
months ago. Then over the course of a
few weeks over the winter break, he did
a 180 turn and went AI first on
everything. In today's conversation, we
cover how David and his team at 37
Signals build software today and how AI
tools are making them more ambitious
than ever before. Why Ruby on Rails
Analytics could become even more popular
than they are today as they are both
well suited working with AI agents. why
taste and beautiful software are
becoming more important and why both
standout designers and engineers who
care about the craft could become more
in demand and many more. If you're
interested in what one of the most
experienced builders in the tech
industry thinks about the practical
utility of AI tools and how these tools
could impact software engineers who care
about the craft then this episode is for
you. This episode is presented by static
the unified platform for flags analytics
experiments and more. Check out the show

other season sponsors sonar and works.
David, it's awesome to have you here.
>> Thanks for having me. Thanks for coming.
I should actually say you're in
Copenhagen. That's my city of choice at
the moment. It's a beautiful city. It's
got so much going for it. And so, what
have you been up to?
>> I'm always building stuff. I have been
building stuff for a good damn three
decades now on the internet. I got
started back in 94, I think it was, when
I first got exposed to it and basically
just never stopped. And in the past six
months, I've been building a variety of
things. One of them is a new Linux
distribution called Umachi.
I switched to Linux about a little over
two years ago, I think, now. First spent
some time on Ubuntu, having fun with
that, and then realizing I actually
wanted to make my own system from
scratch, building it on top of Arch and
Hyperland. So, put a lot of time into
Amachi. It got started as a summer
project in between racing at the 24
hours of Lama. there's a lot of downtime
in that week. So, I just started hacking
on it and it really took off very
quickly thereafter. It's been a truly
inspiring ride to see that even in a
market as crowded as Linux
distributions, there's about 7,000
different distributions out there, some
of them with long pedigrees and many of
them even based on sort of kind of
similar vibes to some extent. There's
room for something new and it's a great
reminder that all the ideas in the world
may be taken and it doesn't matter
because your spin on it isn't. And I put
my spin on Linux. Billachi built the
perfect computer system for me and saw
exactly the same thing I've ever seen.
And whenever I build something that
really just hits the spot for me
personally, there are thousands of
others just like me or close enough to
what I like that they find the same
pleasure and joy in it. Whether it was
Ruby on Rails, Kamal, getting out of the
cloud, any of these things, it's the
same syndrome. Yeah. With with Rails,
you were literally scratching your own
itch. You were just building your own
components and then open sourcing them.
Is that how it started? Basically, I
picked up Ruby in the early 2000s and
really put it to the test in 2003 when
we started building Base Camp and I did
not have a mandate of what to use to
build it. Prior to that, I'd been
working for a lot of client projects
that would say, well, we're building
this in PHP because we have someone who
knows that. So, this is what you have to
use. And then we were building our own
system. We're building Basec Camp. And I
was free to choose. So I chose Ruby and
at the time Ruby didn't have any tooling
or ve not very much when it came to web
applications. So I had to build it all
myself and that turned into Ruby on
Rails which is still going strong. I'm
still very heavily involved with that. I
think in some ways Ruby Rails is having
a little bit of a renaissance now that
it is one of the most token efficient
ways of building web apps. It's ideally
suited for the agent workflows we're
dealing with now. We'll see how long
that lasts. Maybe all the agents are
going to be writing machine code or
assembler in about five minutes. So
maybe that comes to an end. But for the
moment, token efficiency still matters.
And it still matters whether the agents
produce code that humans are able to
read and verify. That may also come to
an end at some point. But as it is right
now, it's uh been a fun ride to just see
these kinds of projects where I'm
scratching my own itch resonate with a
much larger community of people who then
show up and want to help. I mean for
Umachi which has only been around for
what is that just over 6 months now we
have what 400 contributors who've made
code changes to the distribution and on
top of that we have tens of thousands of
people who've installed it and uses as
their daily driver. So, I always love
that discovery of something new, novel,
and inspiring like Ruby or it sounds
weird to talk about discovery of a
operating system that's been around
since what 91, but for a lot of people,
Linux now is that discovery because they
have not been using it on their personal
computer. So, they're seeing it for the
first time. And for me to help a new
cohort of Linux users and hopefully even
enthusiasts come to be because I'm
flattening the curve a little bit. I'm
making it easier to get started. I'm
making the default installation just
look amazing so that they don't feel
like they have to invest 100 hours into
tweaking the system to get going is
really fun. But what's also fun of
course is that both of these things,
both Ruby and Rails and Amachi were not
just hobby projects. I love hobby
product and I will always do those, but
I also like to apply them to business.
So at 37 Signals, we built an entire
business for 20 plus years on top of
Ruby and Rails. We're now running Linux
on the majority of developer machines
because we now have our own distro.
>> So it's obi
people can choose, right? can they
>> well sort of kind of we started with a
with an open choice and then at some
point it just doesn't make sense anymore
in the same way it would not make sense
for someone to be at 37 single and say I
want to write this thing in Django we're
going to use Python and this other
framework even if you have Ruby and
Rails and you're doing that so we
pivoted from an early invitation to play
around that was what when I first
switched to Linux just said like hey if
you want to check it out check it out
then when things got a little more
serious with Amachi I just said let's go
all in for everyone who's on the
technical side of things, not the iOS
developers of course, but anyone who's
working with the web, who's working with
Ruby, who's doing DevOps, they should be
on Linux because first of all, that's
closer to what we deploy. We've always
deployed on Linux. We've been a Linux
shop on the server side since day one.
For developers and system operators, I
actually think it is a material
advantage to be closer to your
production environment and just be more
familiar with the tools. Then on top of
that, of course, we are building this
distribution and we should have as many
hands help out as possible. And given
the fact that I'm the CTO of this
company, I get to set the technical
direction and this is the direction
we're going. Can you just like do a like
just a very short recap of of you know
like how you right and right now where
are you like where where is the business
as a whole and you know you keep you
keep building you keep launching new and
exciting and just cool stuff. I think
Fizzy was the latest one.
>> Yes. So 37 signals was founded in 1999.
It started as a web design firm and then
I joined up in 2001, two years after and
for a couple years, collaborated with
Jason on these consulting projects and
then it was in 2003. We started work on
Base Camp, released it in 2004.
Actually, either the day after or the
day before Facebook went live, which is
kind of a funny coincidence that we were
of that same time and cohort. And within
about a year, we realized this thing was
taking off and we went full-time and
switched from being a consultancy to
being a software company.
>> Awesome.
>> And that's now 22 years ago, a little
more than that. And in that time, we've
released a ton of products. Basec camp
was the first. Remains the biggest and
most important, which is also kind of
funny because you sometimes perhaps have
this delusion that as you learn more and
as you get more experience, you'll get
smarter and you'll have better ideas.
And like, no, there's tons of people for
whom their first idea was the best idea.
And I have no shame in saying that Base
Camp was the best idea objectively in
terms of a business that we've ever had.
And I'm incredibly proud that we've been
able to keep that going and growing and
flourishing for over 20 years. Very few
software companies, let alone software
products, can boast of that longevity
and legacy. But we've tried a ton of
things over those years and had some
other great successes. We launched
hey.com our email service back in 2020
which was a crazy mission when you think
about it.
>> Here is a sector completely dominated by
a single player Google with Gmail that's
a good product.
>> It hasn't really changed in 17 years but
it was really solid and lots of people
are perfectly content with it. They
think they hold this duality in their
head where at once they both hate email
but somehow don't connect it to the fact
that they're using Gmail which I find
curious but either way we launched this
that is not only a competitor to this
very entrenched product that has
probably a greater grasp on market share
in any major category than any other
product I can come to mind of in the US
I think Gmail is something like 85% of
all email traffic, which sounds insane.
Maybe it's 80%. It's incredibly high.
It's basically Gmail and then all the
rest is in this tiny little part of the
graph. So, we thought that after using
Gmail, I used it since I don't know when
I signed up, a few weeks into it, I got
one of those invite codes. That was a
really clever launch and I used it ever
since. So, that's literally 17 years or
something of that of Gmail usage. And
over that time, I built up a lot of
opinions about things that didn't work
quite like I would prefer it to work.
And we put all those opinions into a new
software product. Spend about almost 2
years developing it. Millions of dollars
in accumulative R&D funds. And launched
it in the summer of 2020, which by the
way, time to launch a product.
2020 wasn't great for a whole host of
different reasons. We were kind of
trying to slot in a can there just be a
week where the whole world is not just
insane.
>> Yeah.
>> We finally picked a week. We went live
and then we had the battle of our lives
with Apple.
>> With Apple. I remember that.
>> And ultimately
>> they didn't want to approve your your
app.
>> They didn't want to approve our app
unless we paid the toll fee, the 30%.
>> And they were basically willing to say
you can't be in the app store, which for
an email product like that is a death
sentence.
>> Yes. you have to be on not just mobile
phones but specifically the iPhone. This
is true today. The majority of hey
paying customers are iPhone users
because that's the largest most affluent
market in the US and the US is the most
affluent and market software market in
the world. So for that business to work
we needed to be on the iPhone. After a
twow weekek epic struggle back and
forth, thankfully time to perfection
with WWDC where Apple preferably didn't
want to look like the Goliath squashing
a
>> developer, tiny developer, we ended up
being allowed in and Apple sort of
rewrote the rules after the fact to make
it fit. Um, it was a small victory, not
the ultimate victory, but at least it
allowed us to to be there. And hey,
ended up being an enormous success. In
part, ironically, because Apple gave us
wall-to-wall coverage for two weeks.
When I look back upon that, I think I
wouldn't have gambled like that because
the outcome would have been zero, right?
Like, uh, Apple refuses our app.
>> We sign up 200 people and the app is
dead. What instead happened was they
gave us a multi-million dollar launch
campaign and coverage in all major media
and we signed up tens of thousands of
people in those first weeks. That was uh
an insane event but uh also very
satisfying. And the other satisfying
thing was I just love Hey. I use it
every day. I basically use base camp in
terms of web applications. That's where
we do all our collaborative work. And
then my number two app and many days
it's my number one app is hey because I
just do all my stuff in email. I am
constantly communicating with people.
I'm writing. I'm doing a lot of stuff in
email as many people do. And having that
be a pleasurable experience and a nice
environment and my inbox being a little
more sacred than what happens with Gmail
where total strangers around the world
can just make your pocket buzz if you
have notifications turned on which they
are by default. Just seems insane to me.
Right. this idea that there's direct
access to one of my most important daily
priority lists like anyone can put
something on that insane. Anyway, hey
doesn't do that. We have the screener
and no one gets to reach your inbox
before you've said I want to hear from
this person. And most of the time I say
no to most people, right? Like things
end up in the in the screener and we
have thumbs up. I will hear from this
person, thumbs down, I'll never hear
from that person again.
>> This this is how I reached out. I mean,
we were I'm not sure we were connected
on on X, but I I sent an email cuz your
email is out there and your screener
seems to have worked cuz it gave me the
thumbs up.
>> It did because the screener is me. So,
there's not even AI trying to sus out
whether I want to hear from you or not.
Because what turns out to be true is
it's actually not that ownorous to once
a day go through your screener and say
thumbs up or down because there aren't
that many people in the world. And if
you say no to the annoying pestering
salespeople who within Gmail managed to
read your inbox seven times, then the
workload is much less. And it's very
satisfying, I will say too, because when
I was using Gmail, I would get roped
into this sales tactic that they of
course rely on, which is that like you
write back and say like, "No, thank you.
I'm not interested." And then they would
respond again. And now you feel like,
"Wait, am I now obligated to respond to
this person? I kind of feel like I am."
And occasionally I would end up writing
and even if I wouldn't write, they still
have access to my inbox. So I would hear
from them again next week. They have a
whole drip campaign. They all [ __ ]
do, right? That any outreach is seven
emails. It's not one emails. It's seven
emails. And if you show any sign of
life, it's probably 52. That's just not
how it works. And hey, I say thumbs down
one time, never hear from that person
again. It's actually amazing how quickly
you can curate your garden from that
weed. And then suddenly there's just
beautiful flowers. Suddenly email is not
a chore. So you want to go smell the
roses. Suddenly the majority of things
that end up in my email or things I want
to read is from people I want to hear
from. And that was really the
fundamental mission for us with hey can
we make email lovable again? Email is so
hated by so many people because the
systems are so poor because they're
based on the original premise that email
is just what universities use for
scientists to talk to each other and
scientists have really good manners and
will not pester you 52 times about some
stupid app they want to sell you. No,
they're respectful and beautiful, right?
beautiful ideal, beautiful thought,
beautiful protocol designed for those
norms and those people then you let it
into the world at large and you realize
ah not everyone is endowed with such
norms and such politeness and especially
when sales people get involved. you need
better defenses and for me and for us
and for all our many customers hey is
that defense it is a way to love email
again and I find that it's really
important actually to have a grand why
this is all the way back to Victor
Frankle the meaning of uh of man finding
a why allows you to walk through the
snow when it's cold and uncomfortable
and annoying which many things are when
you're building with computers they are
cold and uncomfortable and annoying.
Now, it shouldn't be that most of the
time, but occasionally that will be
there. And if you have a really strong
why, why are we building this? Who is it
for? What are we trying to do to improve
the world? Even if that's not more grand
than just letting people love email,
it's a lot easier and it's a lot more
enjoyable to then carry whatever burdens
you got to pack if you can set it up
that way.
>> This is a good time to talk about our
season sponsor, Work OS. Having a strong
why is what gets you to building
something great. But after you build it
and start selling it to enterprise
customers, they expect things like SAML,
SSO, directory sync, audit logs, and
fine grain permissions. And those are
not small features. They're systems.
Systems that can take months to build
and maintain. Works gives you APIs,
enterprise ready off, and user
management in days instead of months.
All designed to fit cleanly into your
product. That's why companies like
OpenAI and Traffic and Cursor run on
work OS. Focus on building your product.
Let Work OS handle the enterprise
infrastructure. With this, let's get
back to David and the old way of
thinking versus the new way of thinking.
Putting our your developer hat on like
can you talk talk me through on how how
you built it? You said it was two years,
but was it just one or two people
starting to build it? I'm sure as tech
you obviously must have used Ruby on
Rails a lot. Uh, and then I I don't
probably some some native stuff as well,
but the two years seems a lot especially
because you know you're you're a small
company. You're a nimble. You're a great
developer. I'm you hire great
developers. Suddenly it's been two
years. What what took so long for and of
course it's beautiful product. But right
on the surface I think as developers we
might have this this thing where I look
at it as like two years with with a
talented team.
>> That's the hacker news quip to basically
everything, right? Like I could have
built that in a weekend. I mean famously
stated with Dropbox that I could have
built that in a weekend. We could have
at the original iPod when it launched.
It was like 5 GB bits uh no Wi-Fi uh
whatever less speed than Nomat lane. So
I get that because I also have that same
instinct. I think that is our hoopers as
developers. We think we are gods and we
can make anything happen in no time at
all. And you totally could. You can make
a prototype happen in these days faster
than faster than a weekend, right? like
in in in a few hours we should be able
to have
>> kick off an agent. Yeah.
>> But figuring out what you actually want
to build takes a lot longer and arriving
at something that's worth publishing
takes longer still. At least it does for
us and I think it does for anyone who
arrives at anything good and the
original hey construction was just me on
the technical side. This is actually how
we've started majority of our major
products is either it's just me
sometimes it's one additional developer
but is in a tiny tiny team until we have
a shape until we have a an architecture
and we have a direction of where the
product is going to go. I've found that
you actually go slower if you pour a
bunch of people into a direction that is
uncertain. If you don't know what you
want a million people is not going to
build it for you. You have to figure out
what you want. We can talk about this
later, but this is where AI's very
recent progress is changing things
dramatically. It is now quicker to
arrive at what do I want? But for hey,
it was me and then it was Jason and uh
one designer, two designers, very very
small team trying to figure out the
shape, trying to figure out if you're
taking on Gmail, you can't just do Gmail
in blue. No one's going to buy that. No
one's going to be interested in that.
It's got to be novel, which means it's
well, not just novel, it's got to be
good. It's got to solve problems that
people haven't even articulated they
have with Gmail because the articulation
people have of their problems with Gmail
is I hate email, which as we talked
about is a bit of a misdirection. My
contention is you hate Gmail. And not
just Gmail, but most email systems built
on the old way of anyone has access to
your inbox and all that stuff. But
figuring that out, figuring the shape
out takes a while and it's also fun to
do in this way where you noodle with it
and you don't have infinite capacity.
The original base camp is built the same
way. It was just me on the technical
side. Is this a shape uplogy? There's
shape up thinking in trying to actually
endow the designer with an intention of
how should it work not just how should
it look and figuring out it's also how
it should look product should be
beautiful and they should be unique and
appealing and so forth. So that also
takes time. But figuring out how it
should work is primary. Figuring out
where's the epicenter, what's the most
important part and teasing all that
apart. But with Hey, as with all the
major products we've done, we start with
an absolutely tiny team, often just one
individual on the programming side and
then one or two individuals on the
design side. And then we go, we go, we
go, we go. Suddenly something clicks and
we go like, this is good. There's
something here. And then there's a bit
of a ramp. we take on a few more people
and then when we get within maybe the
last 20% we go okay now we know what the
terrain looks like we can go way faster
if everyone piles in. So one thing that
is super interesting and you might take
it for granted but it's very different
to how most startups uh that raise VC
money which I'm very familiar with uh
and and big companies Uber Facebook you
name it the way projects would start
there is you take the product manager
>> who works with maybe maybe half a
designer
>> and comes up with a spec and then
developers get involved later and what
I'm hearing what is very novel to me is
you take one or two designers and a
developer how you think about designers
Even you recently hired a designer,
Zultan actually, who I'm I'm chatting
with on the side. A great guy.
>> But my sense is you think of designers a
little bit different than potentially
the rest of the industry does.
>> We very much do. Designers at 37 Signals
are not just here to make a spec look
pretty. They're here to find what the
spec should be. They're product managers
in many ways. They are the finders of
the how and the why in many cases
deducing in some cases customer feedback
in other cases just pure intuition and
distilling that into what should we
build and how should it work and then on
top of that they're also responsible for
building it they're responsible for
doing the CSS they're responsible for
doing the HTML they're quite often
responsible at least dabbling in the
JavaScript and the Ruby code to get to
something functional now with agent
acceleration. They do the whole thing,
not necessarily as it will be merged,
but the whole thing in terms of here's
the final shape and design of what it
should look like. But I do think we are
very peculiar in this sense. And we have
found this when we've been trying to
hire designers that many designers
working other companies are not used to
also wearing the product manager hat,
figuring out what we should build and
wearing the implementation hat, shaping
it into CSS and HTML. I found that when
you combine these three hats into one,
you have an individual who know the
materials they're working with, know how
they stretch, know which way the seam is
supposed to be cut, and therefore works
natively with the fabric of the
internet. When you're working directly
in CSS, when you're working directly in
HTML, you're just much more in tune with
what this medium wants. And I find that
that's probably quite similar if you're
a jewelry designer. You should know the
properties of gold. You should know how
it bends and the strength. An architect
should have some engineering
understanding of loadbearing structures
and so on. Not to the degree that the
architect is just going to design the
whole thing and then we start pouring
concrete. you still have uh engineers
helping you out, but the more you
understand the materials you're working
with, the more you're likely to come up
with something that cuts along the grain
and therefore ends up feeling correct,
feeling good. Just a quick hop to Apple.
I think this is one of the reasons why
some of the historic super fans like
Daring Fireball and others uh Gruber
have been disappointed by the new
direction is that Apple used to stand
for these exquisitly designed native Mac
applications which is an dying breed
like they're essentially dead. Now we
have Electron which we can talk about
that too gets way too much hate in my
book. There's crappy implementation of
that, but it's just a web in a box. But
the disappointment with losing that
sense, and I think it's about the same
thing that the Mac, its native
feel has a stretch to it. Like the
button placements, everything you would
call a native application either feels
synthetic or it feels authentic. And
today, it's all synthetic. There's no
nothing authentic about it left. And I
think for the web it's the same thing.
Now the web is a much much larger
platform and therefore it's gotten much
more attention. So there are way more
people working on that quality of it.
But at the large companies it's
exceptionally rare to non-existent to
have that kind of dynamic. I think some
of that is going to change. Agent
acceleration is going to empower
designers to be more capable in these
ways. So the industry is coming a little
towards our fundamental stance which is
funny too because the same is true on
the programming side. When I talked
about base camp being a product of just
me on the programming side for launch
that for so long sounded unambitious or
even wrong or even to the point of lying
from some quarters of the internet like
yeah but you can't build anything real
anything meaningful anything big unless
you have a team that's much larger
because it's just going to be a toy
product right and my insight from the
start was that's of course [ __ ]
because you just haven't used Ruby on
Rails you just haven't used the
acceleration that's possible if you use
better tools. Now we're all realizing
that we're using realizing oh so if you
use agent acceleration a single
individual actually can build something
highly valuable team.
>> Yes.
>> And that's just fun to see that like the
industry is coming towards oh smaller
teams are better because now the cost
savings you have on the logarithmic
curve on communication cost starts to be
relevant. And this is one of the things
maybe we can talk about this where agent
acceleration is really changing the
bargain between junior developers and
senior developers. Let's talk about
this. But before we go into that, do I
feel that you very much value software
engineering as a craft, which is very
obvious, but what I'm sensing is you're
valuing design, user experience, design,
designing on software design, like you
know, like building stuff that feels
good. May that be software, hardware,
you also value that as a craft and and
you look for it like the these two
things. Do I sense this correctly?
>> Hugely. I mean, I think aesthetics
is truth. When something is beautiful,
it's likely to be correct. I think this
is true in mathematics. This is true in
physics. This is true in a lot of
different domains that when you arrive
at something that has the correct
aesthetic quality. It's like we have an
intuition that guides us towards that
level of beauty because it also happens
to be correct and noble and something to
aspire for. I also happen to believe
it's what makes people happy. Being
surrounded by beautiful, well functioned
objects is a key part of happiness. In
fact, I'll put it in a negative way,
too. One of the great sources of anxiety
and frustration is when everything is
[ __ ] When everything is laggy, when
that touch interface doesn't register,
when you have to restart it, when you're
calling a travel agent, they can't do
something because their old shitty
cobalt system won't let them. Right? The
world is full of not just in
shitification. That is things that went
from being good to being bad to just
plain bad, just plain awful. And I think
it is a serious source of malaise for
civilization. that we could literally
raise the bar of human happiness if we
were surrounded by more beautiful items,
more beautiful systems. Both in the
sense of its aesthetic exterior
qualities, but just as much in terms of
its aesthetic interior qualities,
because I find those two things are
usually in perfect harmony. The reason
why Steve Jobs cared about the inside of
the box was because he intuitively knew
that the kind of people who care about
the layout of the print board will be
the kind of people who sweat the details
on the user interface will be the kind
of people who sweat the ergonomics of
opening the case. So I think there's
essentially no choice if you are a
person who is attracted to these
aesthetics which I think is everyone.
there's just varying levels of u
awareness about whether you are or not
but that you want to make it all
beautiful and for me Ruby in particular
has been this seinal language because it
produces the most beautiful code in my
book there's barely even competition
like there are other things that can be
beautiful in a way like I find looking
at small talk for example very beautiful
in its minimalism but not the house I
want to live in Ruby is the house I want
to live in because it's got that
aesthetic equality while not being rigid
about its ideology which is a very rare
aspect too. I more often find now we can
refer to IV again is that when someone
is obsessed in this way they are a
little narrow-minded like that's the
trade-off that's the price and I find
that Ruby has somehow managed to be both
broadscoped yet also intensely focused
on on this but overall we have to have
beautiful things we have to work with
beautiful tools we have to produce
beautiful fluid interactions this is how
we should see ourselves as crafts people
that we care about polishing it until
there are no splinters left. How is AI
changing how you work and how do you
think it's changing your craft or just
let's just talk about the craft of again
you're you're hiring people in 37
signals who similarly care about design
and and software craft's quality how
it's changing what you get out of the
craft or how it's how it's making it
better or or worse in some ways I I I
just want to you know start with like
how has your view changed because the
last time you you talked in in length
about this that was on Lex Freriedman's
cast and you were still rightfully so
very skeptical of of AI. It was a
different set of tools. It didn't work
as well and I think you you went there
bashing it pretty hard but things have
changed since.
>> This is a nuance point and maybe it's
self- serving but I don't actually think
my opinions have changed. What have
changed is the circumstances and the
facts which uh is is something I called
out on that show and in many other
writings was right from the get-go I
could see that we had something new and
novel here that was going to change
things. Chat GBT its launch what three
years ago was clearly and obviously even
at the time something you would mark on
a timeline. You're like here are all the
important things that happened in the
history of computer science or the
world. Yoinks, there is the launch of
Chat GBT and interacting with computers
in this way and seeing them reason, even
if that's still a disputed term perhaps,
but to me it seemed obvious that these
things were freaking smart, smarter than
me in many ways, whether those smarts
came from parenting
weights and data.
So what? We don't know how human
consciousness works. We don't know how
human wisdom or intelligence works.
barely. So, let's not be so categorical
about what constitutes consciousness or
intelligence. At least, I find no
utility in that distinction, even if
it's fun to ponder. But what I found
with the early models and the early
ergonomics where it was autocomplete,
where it was co-pilot and cursor in your
editor trying to guess the next
character,
>> it it would be sometimes littering it.
Right.
>> Yes. I found it infuriating. I found it
as we're trying to have a conversation.
You won't let me finish a sentence.
You're constantly trying. Was this what
you meant? Was this what you meant?
You're like, shut the hell up. Can I
just finish a thought? And I thought,
even if it is capable of occasionally
accelerating, it's also wrong so often
that that acceleration feels like a
nuisance, even if it's somehow net
positive, which it wasn't for me. Or
maybe I gave up too soon. But I just did
not enjoy that. I didn't think the
models were good enough. I thought the
way of using the models with
autocomplete versus agent harnesses was
just dreadful, annoying. In fact, to the
point that I got a little pessimistic
about the direction of the industry for
a hot second because I thought this was
what we were all going to do. We're all
going to sit and do tap tap tap.
No, thank you.
>> Well, cursor even have they had I even
got one of these one of their swags was
a tap key.
>> Exactly. which which felt very and I I
haven't I I got it from them. It's
really cool, very well designed and all
that beautiful design, but
>> but dystopian
>> dystopian
>> when I see that and I remember that was
a meme for a while just we only need
three characters on the keyboard, right?
I thought of that episode of uh The
Simpsons where Homer puts a mechanical
bird on the keyboard that just dips down
and hits enter because all he's been
doing is hit enter. Except suddenly
there's a warning about the nuclear core
overloading and the bird just hits enter
and the whole thing burns down. I'm
like, "Wow, that's quite a parallel."
The Simpsons really does predict
everything. But I did not like that
style of using it. As much as I retained
my enthusiasm for the general direction
of travel because it truly is amazing
and the amazement to me I tried to
embrace as a tutor model as a pair
programmer who doesn't drive it was
amazing to have chat GBT and the other
model just be there for like I don't
understand this fully here's a piece of
code here's a question can you tell me
why it works like that can you tell me
what's wrong with it because that's how
I've been using the internet since day
one right that's what Google was for
here's an error message. Here's a
concept. Maybe I find something on Stack
Overflow with some passive aggressive
nerd telling everyone why he's so smart
and then at the bottom there's the
solution I'm looking for. Or I don't
find it at all and that's just kind of
frustrating. With the chat GBT model, I
very often got a really good
explanation. Yeah, this was actually I
talked with a game developer Jonas
Tyroller who who built this really cool
bestselling game. I loved playing it and
this was during this time of of the tab
completion and he said that in his the
way he works is he just turned off all
auto completions in his ID uh because he
got annoyed by it and then every now and
then he went to chat GPT to ask
something or have a longer thing and
then he had the mode of like I'm
thinking and I'm doing this stuff oh I
need some help okay here's the specifics
and I'm taking and somehow it felt that
you know like he just he was in the zone
the whole day by controlling it and and
somehow those habits sounds like You
know, you're saying the same thing. It
kind of took it away from you. Us.
>> Exly. Exactly. And I did get a little
worried that that was going to be the
direction that we were all going to be
the bird and I didn't want to be the
bird. Then I was like, well, what should
I do instead? Maybe like farming
potatoes. Like that's a long tradition
here in Denmark. Maybe I could take that
up.
>> But then thankfully two things happened.
A clot code in what is that? starts in
the spring, gets going sort of over the
summer, then by the fall has some
traction on a new way of using agents to
help you code where with the agent
harnesses, right? This is really where
we transition from AI to agents.
Suddenly the AI has tools. It can use
bash. It can use everything you got on
your terminal. It can call the internet
in for appropriate information. it it
just is capable of doing more than just
reasoning about a thing you gave it uh
or input from a source context file. And
then the models opus 45 to me is the
other one of the other points we're
going to have on the line where it's the
first model that continuously and
consistently would shock me with the
quality of its output. it quality of its
analysis on the basis of vague inputs
and even more importantly the quality of
its output. It produced code I wanted to
merge without
very much if any alteration and if I did
want to do alteration I could tell it
and it would remember and it would not
make the same mistake next time. that to
me the combination of those two things
was the unlock
>> and and you have a high bar like you
have a really high bar
>> incredibly high bar I as we've talked
about now at length like the aesthetics
of the output really matters if I'm
going to look at it and I'm going to
review it I'm going to give you another
anecdote in a second where those things
don't even play in but when I'm using
agents to work on Ruby code I want their
code to look as good as mine I'm not
going to merge their stuff if it's
sloppy no more than I would merge the
work of a junior developer who has not
yet fully internalized our style and so
forth. So I wanted to be on par and on
parody and the early models just
couldn't. That didn't mean they couldn't
produce working software. At least some
of the time they could. I'm very
impressive. I mean I remember when I did
my first snake game and I'm like holy
smokes. I've been wanting to do this
since I was 6 years old. Like I've been
wanting to I have this idea. I want to
get it into a game and I was able to see
that in I don't know a few 30 seconds.
It was done with the game. copy paste
the HTML magical experience, right?
>> So, I think that ramp was very
interesting because it actually took a
while until we found this form factor of
the agent harness of the terminal
interface.
That to me was the the big unlock from
this is interesting. I want to have a
conversation with it to I wanted to
write my code. I will now start any
project I'm starting with. I'm starting
agent first and that's a massive shift
and it just happened from November 27th
I believe is when Opus 45 dropped. Now
there are other people who have
different points they felt like oh is
Opus 40 or
>> maybe some people talk about Sonic 37.
There are other earlier checkpoints but
there I do feel like there's a general
consensus I can lean up against that
capy and others have expressed like yep
it was right around end of November
early December. Everyone who works
worked at larger tech companies, it was
the winter break because people just you
know like like the whole industry shuts
down for 2 weeks say for a few places
where you're on call but again no
production work happens across the
>> industry to play with this.
>> My sense was that people were playing
with it because you give it your side
project you never finish expecting not
to finish and then they also got
shocked.
>> Yeah.
>> You're done and that was just a complete
sort of break, right? Right? Like if
this was a movie, you'd hear the scratch
sound like you're like, "Wait, what?
Revine, what happened?"
>> I feel it was the most collective shock
which happened individually and then
people came back in January and everyone
especially because a lot of the decision
makers who are you know like CTO
engineers etc were not as hands-on but
they were hands-on and a lot of them
it's this weird thing where they came
back and they start to mandate or like
say all right you guys need to use this
because I've seen the future. I've
literally used it you need to see it.
So, it's we're going back to a little
bit of hardware like people were trying
to give, you know, like the the new
hardware into people's hands saying you
need to experience it cuz you're you're
not going to believe it, right? There's
something with this as well where you
you really don't believe it. We can talk
about this and whoever's not tried it or
not had that aha moment. I don't think
we can convince them.
>> This is another one of those cases where
words just are not effective. You need
to sit down in front of Open Code or
whatever harness that you use, use one
of the frontier models, start with that.
Start with Opus. I'd say start with
Opus. It's the best frontier model.
Other models are better at other things,
blah blah. But if you're just going to
work on a piece of code and you want to
see what the current frontier is and if
you I mean I'd be shocked if any of your
listeners haven't done it already, but
if there should be some left, now is the
time. And I don't even want to say in
the sense I I found it really offputting
this trend on X where unless you've
internalized everything there is about
AI, like you've been left behind. Shut
up. First of all, patently not true. you
could literally pick up everything in
the next three weeks. This is the other
magical thing about this kind of
project, right? Like or or progress when
if we had been having this conversation
in spring of last year, everyone been
like MCPs, MCPS, MCPS. And do you know
what? You can now manage to just have
jumped over that entire things and go
straight to CLI and skills. That's just
worth having in mind that this FOMO that
unless you're up on all of it as it
happens play by play, you're left behind
is complete and utter nonsense. That
being said, I can still appreciate that
some people were early. And for me, Toby
Lutki at Shopify is the main individual
who saw this and saw the changes that
were coming from it way earlier than I
did and have really helped drag me into
this by constantly sending me like,
"Hey, you look at this, look at this."
And I do think that's actually quite
helpful. It's quite helpful to be
surrounded by people who have a higher
faith or maybe their eyes are a little
further up. Like my eyes tend to be
relatively close to the road like right
in front of me and some people have a
gaze that a little higher up and
sometimes they see things that don't
come to pass. In this case, Toby saw
exactly where we were going two years
ago. And I finally saw it because the
road came to me in December. And it's
funny because along the way I kept
saying like, "Yep, when the models get
good enough, when they can do all this
thing, it's going to be amazing." and
thinking wow it's going to be I don't
know 18 months two years maybe it's five
years it's very hard to predict these
infliction points and I think the
industry itself didn't even predict the
infliction point right you have an
entire city Silicon Valley and
surrounding areas San Fran focused on
making this happen but predicting
exactly when the hockey stick starts
hockeying is very difficult but then it
happened and now my daily work is very
different
>> so so what is your daily work. Now,
>> my daily work is
agent first on everything.
>> Going agent first is a good time to
mention our season sponsor, Sonar. When
shifting to agent first work, one thing
that inherently comes up is the quality
of the code. Sonar, the makers of Sonar
Cube, is deeply rooted in the core
belief that code quality and code
security are inherently linked. High
quality code is naturally more resilient
and as agents start writing code at a
massive scale that verification layer
becomes your most important security
parameter. This is where solutions like
Sonar Cube advanced security are
valuable. With this new malicious
package detection, advanced security
provides a real-time circuit breaker
automatically stopping agents from
pulling in unverified or risky
thirdparty libraries before they ever
hit your pipeline. The impact is
measurable, too. Developers who verify
their code with Sonar are 44% less
likely to report experiencing outages
due to AI as per Sonar state of code
developer survey 2026 report. It's
really about closing the gap between the
speed of AI and the reality of
production security. What else is Sonar
doing to help reduce outages, improve
security, and lower risk associated with
AI and agenda coding? Head to
sonarsource.com/pragmatic
to find out. With this, let's get back
to David's agent first workflow.
>> So, specifically cloth cloth code. Uh I
use open code open code. You use open
code.
>> That's my main harness. I also use cloud
code a little bit. They unfortunately
got that early lead. Opus is currently
the best model. So then they started
thinking a little bit in that like the
game is single match instead of thinking
it's multiple rounds and yanked their
subscription from open code. So if you
want to use your Mac subscription, you
kind of have to use their harness, which
I don't love it. I think it's a mistake.
But leave that be for a second and let's
just celebrate the fact that they have
the best model and Opus for 45 46 is
also nice but 45 to me was the
inflection point
>> and it creates a lot of competition
because everyone wants to catch up and
overtake them now
>> of course and especially because you see
Anthropic's revenues I think start of
the year they're at 9 billion few weeks
later they're at like whatever 14 now
they're at 19 or something it's just the
craziest rocket ship you could possibly
imagine which is inspiring all this
capital to be deployed for competitors
and so forth which is wonderful great to
see so even if I don't love everything
that they do and cloud code is not my
preferred harness manage to hold two
things in your head at the same time
this is what I also try to do even with
Apple which I have serious griefs about
how they operate and act as the
gatekeeper and all the other nonsense
we've talked about and then I also keep
my I just love computers hat on and go I
like the new Neo I might even buy a new
Neo and just see what is possible at
$500 for Opus I have no qualms s about
using Opus. In fact, whenever I feel
like uh this is a really hard problem, I
go to Opus right now, but I also use
other models. And one of the things I've
incorporated into my flow is to kind of
have two models going at the same time
at different speeds. So, I use T-Max and
I have this layout thing that's built
into Amachi where it'll start my new Vim
editor on the left side and then it'll
start two panes on the right side. On
the top is open code running Kimmy K25
and on the bottom is Opus running in
cloud code and then at the very bottom I
have a strip of terminal and almost
everything I started in one of the
agents and I tell them what I want. Then
I hop over to Neoim. First I do uh space
gg to look at the um lacy git diff on
it. Once this is changing if it looks
correct I'll just commit. We're we're
done. Great. and then sometimes it
doesn't. It'll correct and I'll I'll go
in and alter the code myself. But the
ratio and how quickly the ratio changes
is still astounding. I went from early
November last year, I'm code first
everything. I started the editor,
I'll spend whatever long it is and then
at some point if I get stuck or if I
want a second opinion, I'll go ask my
friendly clanker to give me a second
opinion. That's just not how it is
anymore. Now I start with the agent. Now
he'll give me the draft. I'll review the
draft and I'll make alterations if need
be. And then just recently I flipped it
even further. So we're working on a CLI
for Base Camp so we can get full agent
accessibility for Base Camp. It's
astounding. First, actually, let me
rewind. As soon as I got pilled on how
good the agents were and how capable
they were, I immediately tried to raise
my gaze up towards the end of the road
and think, do we even need MCP? Do we
even need CLI? Do we even need anything?
Can't the agent just figure it all out?
This was when I installed OpenClaw. So,
I installed OpenClaw on a VM and I
thought, what should I do here? Let's
see how far we can push it and what it
can do by itself. So I thought I want
this claw in base camp. I want this claw
in Fizzy. Let me just try to invite it
as it was a human. So I just wrote it.
Can you sign up for Fizzy? I'm not
giving you any tools. I'm not giving you
any MCP. I'm not giving you CLI. I'm
just telling you it's at fizzy.do. Go
sign up. And you see it. Chuck along.
And then yeah, I've signed up, but it's
asking for an email address or I'm
trying to sign up. It's asking for an
email address. I'm like, oh yeah, right.
You need an email address. An agent
doesn't have an email address. Hey, go
sign up for hey.com. I'm like, it's
going to fail this one. And it's Chuck,
Chuck, Chuck. Uh, I've signed up for
Hey.com. Here's the password. Write it
down somewhere safe. I'm now also signed
up for Fizzy. I got the confirmation
email in my inbox. We're all good. What
do you want me to do? I'm like, what?
Are you telling me that you could
one-shot signing up through a browser to
these things? Now, maybe that shouldn't
be surprising. Maybe that was already
possible with Sonnet 3 or one of the
early models. I don't know. But when you
experience it yourself on your own damn
claw that you're just telling over
Telegram to do something and it's
signing up for products autonomously,
that's pretty startling. It was for me.
And then the next step I went like,
well, if it can sign up for Hey, and can
sign up for Fizzy, let me invite it to
Base Camp. So, I send it an invitation
to its own email address. Here's the
invitation link to Base Camp. Can you
just jump into the AI labs lab uh
project that we have and introduce
yourself to the team? go, "Hey, I'm
David's assistant. It's very nice to
meet you all. I've read back the
transcript a little bit. I see you're
all excited about these things." And you
just go again, "What? What?" And that
was fun because it showed me that even
if it was going to take a while, it did
take a while. It took a while. This is
um agent terms. It took I don't know,
seven minutes. That was like, "Oh, it
feels like eternity." But it was able to
do it. And that seems like the end
state. The end state is that agents will
not need any of our accommodations. They
do not need any on-ramp. They're not
coming on a little uh wheelchair.
They'll be coming on bionic legs and
running five times as fast as you in
about 2 seconds, which we'll get to in a
second to the speed aspect of it. But
then you also realize, okay, well, I
can't just sit around fiddling my thumbs
until AGI happens. Let's build for
today. And that's what we've been
building for Basecam. We've been
building CLI. We're going to build it
for Hey, we're going to build it for
Fizzy. We're going to build for
everything, even probably some of the
legacy products. And what I love about
the CLI, as much as I also love it about
these harnesses, is that they validated
the fundamental Unix philosophy from
like whatever 71. You should just build
small tools that can interoperate with
pipes and you can
>> that's philosophy, right?
>> It's the total Unix philosophy. And that
is actually the magic to me about seeing
everything having a CLI. It's not that
Base Camp is easier to use now with a
CLI. No, no, is that GitHub also has a
CLI and Sentry, I don't know if they
have an CLI, but they have an MCP that
you can tie all these things together
and now you can tell an agent, hey, we
have some errors in Sentry. Can you go
check them out? Then post a write up to
Basecam iterating what's wrong. Then go
in GitHub, come up with a pull request,
post a comment back to Base Camp when
you're done. And now we have a central
right base cam where we're following the
work as it's going on while we have an
agent doing work looking things up. And
again, when we try to talk about it and
relay it, I guess some people can see
it. And now OpenClaw has enough videos
on YouTube and so forth so you can get
at least a passenger ride. But try it
yourself with your own product, with
your own tasks and with your own prompts
and you will be pilled. You will be
simultaneously
incredibly excited for what we've been
able to make sand do. The silicon, the
chips, the weights, the whole thing.
And then also a little bit anxious about
where it's all going to go. And it's in
that tension that I and probably anyone
else who's been pilled on this live,
right? Wait a minute. If we're already
here, what does n 18 months from now
look like? Like if at the last 3 months
we've upended my entire understanding of
what's possible with computers, what's
the next 3 months look like? What the
next nine months look like?
>> Yeah. This this this is where like I I
was a little bit on on your end for a
long time and I think I still am where I
believe what works and I'm always
skeptical of projections. Mo Moore's law
broke down at some point. I I live
through everyone said it will continue
forever and you know and then it broke
as we all suspected it would
>> but then it found another way. I think
it's the good point about the Moors law,
right? It broke for individual cores.
Yes. How much can you push that? And
then we just went, well, what if you
just had what's the latest chip? 256 on
the AMD 10 chips, right?
>> And even when performance broke, we we
we went into power consumption and size
and all of those things. So, yeah, like
but it's it's harder for me to also just
to say, oh, it's going to stop here
because we've seen it grow. We we know
the approaches that they're taking this
larger and larger training sets and it's
been working so far. And there's also
the bitter lesson which I think I I
think is a it's it's such a short paper
that it's just so worth reading. I think
it's one of probably the most popular
papers outside of academic circles.
>> Yes.
>> Because it just lays out this thing that
we we don't want to believe that. We
want to believe that our knowledge our
understanding is superior that you know
you and me knowing how to code or me
putting in these 15 years or however
long it's been it's special. Sometimes
it shows that it's it's not as special.
What's interesting actually is like
right this second this snapshot in time
it a little bit is and this is a funny
bification that's happening junior
versus senior developer is that the most
successful and applicable agent
acceleration that I've seen at 37 signal
has been from the most senior people the
people who are able to validate whether
what the agent produces is suitable to
be deployed to millions of people. There
was just this story yesterday about some
of the major outages at Amazon.
>> Yeah.
>> And Amazon's own internal analysis
essentially pinned that we can no longer
let junior programmers ship agent
generated code to production without
review. And the problem with that is
first of all I think that's the
realization most companies are now
having across the industry. Whenever
it's mission critical for something of
that nature, we cannot yet rely on the
agents to abet it at all and a and
junior programmers are not capable of
figuring it out. Therefore, their role
is suddenly more tenuous than it was 6 n
months ago because a senior programmer
can and this is why senior programmers
are getting so much more acceleration.
They're able to first of all work in
parallel with lots of agents but
critically examine the quality of the
agent output and have a high degree of
confidence of whether this is going to
work or not and redirect them if not
because this is what made them senior in
the first place. This was the role that
they had that they had the uh long
insight and history and overview of the
architecture. How does it all fit in? Is
this going to work? Is this not going to
work? This was the role they played to
junior programmers. But now they can
play that role to agents and agents are
faster at following instructions and
redirections. And suddenly you have
senior developers who can 5x 10x their
individual productivity. And now this is
the second order effect. If you manage
to 5x or 10x a senior developer, that
person's value per hour just went up
10x. Now take that hour instead of that
person spending it with the agents just
shipping stuff and making things better.
They spend that hour as they would
before teaching a junior human how to do
things better. There's something in that
equation that's in play right now and
it's not clear how it's going to map
out. Now one way it could map out is
that the agents will get so good that
they stop making mistakes. They become
senior in their capacity to ship working
code. This is what my bet would be if we
look x amount of time forward because
this is what just happened with cars. So
self-driving Teslas now drive better
than humans do. Not all humans, not in
all circumstances, but on average. It's
very possible that if we're able to
delegate the mortal risk, the highest
criticality we basically deal with on a
daily basis sitting in a metal tube
along other metal tubes that go 60 m
hour where you can die if someone makes
a mistake, we delegate that to an agent.
Well, they can probably figure out how
to make the code work too, right? So, I
do think it's coming, but who knows
when, who knows how. Right now, we're at
a stage where the bulk of the benefits
are acrewing to the most senior
developers. And also I wonder just like
with self-driving like you realize
there's always KV. So, for example,
inside companies where it matters. When
you're a startup, you have zero
customers. It doesn't matter. You can
oneshot it and it doesn't matter if it
doesn't work and it, you know, it
crashes. But inside these companies, uh,
at Uber, um, I just got details on how
they're adopting AI and and they have
all these tools, cloud code and and all
these things. But what we realize as
well when you just put it in there, they
have all these internal monor repos.
They have their ticketing systems. They
have their slack. They have so much.
They have their RFC's design documents
on on how and why they have this jumble
of a mess uh with microservices which
which was fun way that we we originally
connected like many many years ago. But
what they found is they built a bunch of
internal systems, a lot of it to help to
feed NCD's agent harnesses and now
they're working better. But you know
this where we are right now is is
there's and this is why if you're a
senior engineer in one of these
companies or a staff engineer at like
Uber and you move to Google suddenly
you're not going to be as valuable as
efficient for a while until you learn
all the systems. So I I wonder if just
like with self-driving, you know,
self-driving works great as well. I was
in SFN and LA and way most they they
drive so nice. Like
>> my Teslas was driving in LA driving us
to the airport every time. The whole
family I sit peacefully watch the road
but do not steer at all on that entire
journey. Well, except my my weimo got
stuck because a a truck was parking on
on a narrow street and a car had a bike
shed and I I I I knew that it should I
should not go there, but it didn't know.
So, human oper operator came in. But
anyway, but even with Whimos, you know,
like there's there's things like there's
they drive in pretty good weather.
They've been mapped out. So I wonder if
in software engineering I I wonder if
this has these parallels where we have
all of you know like these companies
have their their specialized
landscape and once you map it once you
do all the tools once you figure out
these things and with self-driving it
took it took 10 years right like I was
at Uber when they bought the
self-driving thing and we were hearing
in the news that you know next year it's
all going to be over for drivers and no
>> yes there are not going to be steering
wheels anymore which by the way is an
amazing anecdote because it just shows
Elon 's total faith in his mission
because in 17 when he made that
proclamation, it was an AI. It was
500,000 lines of handcoded C++,
>> right?
>> Like that model was never ever going to
get us to the full self-driving. But he
had just total faith in the vision. And
then eventually, hey, here come along
comes AI and it's so good. And if you
train it on billions of hours of road
use, it actually can do it. And it can
do it better than most humans. In fact,
I'm a pretty good driver. I'd like to
say I'm not the best chauffeur because
my I don't know impatience have a
tendency to provoke the throttle. Uh
that's not always as pleasant for
passengers as it is fun for me. And when
I let uh the Tesla autopilot drive, it's
just the best chauffeur in the world.
It's just perfectly
>> better than you.
>> Better than me, better than the queen's
chauffeur, I think. like it's throttle
actuation and deceleration is godlike.
It's actually agi like or as like in its
application within that narrow domain.
And of course, when we get these
anecdotes and these examples of holy
smokes, not it didn't take 10 years for
the self. It took 10 years from the
proclamation, but what they were doing
for seven of those years had nothing to
do with what they're doing with FSD now
because the FSD that's based on AI
hadn't been running for that long. But
the inflection point of I think it was
131, FSD 131, like the first version,
you're like, "Wow, this is pretty good,
but like I better pay attention." 132
140 142
over the course of 18 months we went
from yeah it's pretty good but like I'm
going to pay attention here to why is
there steering wheel and that
acceleration that short period of time
of course is something people look to
when it comes to programming go like
well if we're here now and senior
programmers still have to review it
because otherwise you're going to get
all your whatever four severity eight
down times at AWS because some AI pushed
out some nonsense. What is it going to
look like when they take the jump that
FSD did over the same period of time?
Now, I also think you can go completely
crazy trying to just sit and soak in all
of that. This is what I tried to do over
the past year. Go, I'm really excited
for where this is going, but I'm also
going to deal with what's possible today
and what's enjoyable today and what we
do right now. I'm not going to try to
plan what my life looks like 12 months
from now when maybe we do have AGI or we
don't. Now, there are other people who
do that very well. I just watched an
interview with Leopold on Drakesh from
last year. He's thinking like what does
2030 look like? What does the whatever
10 gawatt data center look like? I'm
like I I'm very glad we have individuals
who put thought into that because that's
not my favorite spot to be and I think
most people are not that good at
polishing the crystal ball.
>> No. Well, I I mean this is a little bit
unsettling as a software engineer in the
sense of like clearly this is where the
industry wants to go. This is where a
lot of effort will be put. There will be
a lot of businesses, software businesses
built on this. A lot of VC money raised
on this by the way who are going to
tackle this and they will either like
succeed or die. That's what that's what
these companies do. But today, what do
you see at at 37 signals uh with
software engineers? You you of course
have mostly experienced engineers,
although you did hire junior engineers
as well. How is their kind of work
changing? How is their satisfaction with
with work change? Because that's also a
thing, right? We keep arguing about like
is is it making us more miserable at
these things? Is it what we want to do?
And how's it changing for you? Right. I
think it's
>> that's the biggest revelation actually
more than even the capacity of the
agents is my enjoyment running them.
When I was on that leg interview last
summer, I was talking about you know
what I don't want to be a project
manager for agents because I had the
mental model of a project manager of
humans and I thought like that's not
what I enjoy. I don't want to be that
far away from the production. I want to
be in the mix. I want to have my hands
in the code. What I failed to realize at
the time was that running a bunch of
agents feels less like being a project
manager for agents and more like
stepping into this super mech suit where
suddenly I don't just have two arms. I
have 12 and I can now look at seven
screens at the same time running five
keyboards. I'm still the one doing it
even if I'm not typing this as a keyword
in a program. I have been hyper
accelerated as a programmer. It's a
different kind of programmer, but it
still has the same affinity to
aesthetics, at least when I'm producing
Ruby code. And I'm able to combine that
while being vastly more productive on a
bunch of things. It's also like getting
an incredible brain upgrade on even
assessing issues. One of the pilling
moments I had was before the release of
Omachi 3.4.
I went into GitHub and we had I don't
know 250 PRs pending and I kind of just
sighed a little bit and like 250 PRs if
I spend I don't know 15 minutes on each
PR like how long is it going to take
before I get to the end of it and I
thought you know what let me try
something else let me just try to ask
Claude to I'm not even doing anything
with a system I just do review URL and
the URL is the issue or is the PR are
shocked In
90 minutes, I think it was, I processed
100 PRs. And it wasn't that I merged all
of them. In fact, I'd say I merged a
small minority. Maybe 10% got merged as
is. Then maybe 20% got merged. But with
Claude's implementation,
>> the programmer had correctly identified
an issue
>> but hand rolled some code that I could
see I didn't want to keep or sometimes I
couldn't even see it. I just asked
Claude and they say like ah it's not
quite right. And then I just asked
Claude, can you just clean room this?
>> This is the right problem. Let's fix it
but let's do it right. It would do it
right away in exactly the style as I
would have written the rest of Amachi.
Now this isn't the high code of
something. It's mostly just bash code,
but there's still a shape to bash code
and how you want it to look and can it
feel coherent with the rest of project.
Agents opus in this case would just nail
it. And then the second half of it was
split between 25% thinks I then just
realized I just don't want this. It
shouldn't we shouldn't have it. And 25%
claude telling me maybe there's
something here, but it's really not a
good implementation. We don't have a
straight shot to making a great one. 100
issues in 90 minutes. And I sat back.
This would have been a week's worth of
work, days at the very least. What the
heck? And even more than that, Claude's
analysis of at least half the issues
pertained to things I knew nothing about
where it was undeniably
a smarter, better reviewer, programmer
that I could ever dream to be. Well, not
dreamed to be, but wasn't that
>> moment? No, but you would have not put
in the effort. This was why the PR sat
in the first place. In many cases, I
would look at it and go that
>> I think there's something here, but like
then I now have to read up on this debug
thing. I have to figure out is this the
right way of doing it. I don't want to
just merge something that then has other
issues. And to be able to do that agent
accelerated was one of top 20
programming moments. I I like how you
put agent accelerated and it sounds like
it's especially efficient for work that
is waiting on you but you don't want to
do it or you're not as skilled of doing
it but it's a hassle to delegate because
again like you have a team right like
like like you but you probably didn't
delegate it because you probably knew
that it wouldn't make it faster or
better. So I I I wonder if there's a
part of AI that because we talk a lot
about like you know like companies love
to measure especially larger ones like
efficiency PRs and they want to see
impact but about the impact of doing
work that we would have not done before.
>> That's the kicker for me. That's the
fact that the pie is just exploding
right now. It's not growing. It's
exploding. The number of projects we
have tackled internally that we would
never even have contemplated starting on
are legion. We had a great project where
normally on performance work you worry
about uh P50, P95, P99. Jeremy, one of
our most agent accelerated people went
like what about P1? What about the
floor? Can we fix the floor? What is the
floor? And he went like well right now
our floor is I forget what it was 4
milliseconds. Let's say that, right?
Well, actually 4 milliseconds can add up
if you have a bunch of fast requests.
They can still it still matters. and he
just went like, "We're gonna do P1.
We're gonna optimize P1 literally the
fastest 1% of requests. We're going to
make them even faster." He took it from,
I think it was four milliseconds to less
than half a milliseconds. He 10x the
performance that I was like, I would
never have signed up on this and he did
the P1 project over a couple of days as
like a side gef because now he could.
>> Now he could because he had a hunch. He
had an intuition that there was
something here. He let agents run with
it and the number of PRs that like all
right we fixed this we fixed this I
think total the PR the P1 project I
maybe misremember but I think it was
like 12 PRs like just fixing all sorts
of things where I look at the single PRs
I'm like yeah actually okay yeah makes
sense I look at the total sum of it
you've changed 2500 lines of code you're
like you've done that in a few days
>> it's so I've never heard anyone do P1
because it just it feels like a vanity
experience it makes no business sense I
I This is not true, right? Cuz
everything adds up. But but you know
what I mean, right?
>> I know exactly what you mean. And this
is exactly why the explosion of the pie
suddenly lets us look at problems we
would never have contemplated looking
before. It's funny. I remember this
scene from Terminator 2 where they found
this chip from the Terminator in the
first movie and he goes like, "This
thing gave us ideas we would never have
investigated before." And like there's
some beautiful parallels here about like
maybe we're about to build the
Terminator, the cliche, but also we're
getting ideas, we're getting ambitions
we would never have looked at before
because suddenly the cost of exploring a
hunch has just dropped by a
thousandfold. I do this all the time
now, too. I'll give it some vague crappy
instructions just because like I have
this fleety idea. I haven't even
crystallized it into a neat prompt. I
just want to see something. It'll And
then I go like, oh yeah, delete as in
revert code back to normal. I like
before I would be a little more precious
about 75 lines of code because it would
have taken me two hours to do him. Now
there's no residual value to any of this
stuff and I can just go like show me a
draft. I feel like a little bit like a
king where you just go like show me the
the analysis of the farrung regions.
Where are we with the tax recip? And
this boy is like, "All right, this uh
servant is like, "Yes, I I shall do so
and return in 3 weeks." Except like you
can just wave your hands around. And
agents just come back with answers to
stupid questions, terrible ideas. Then
suddenly it wasn't so terrible. It was
actually a great idea. And you go like,
"Wha, I did this with I haven't even
pulled the trigger on it yet." But one
of the things with the Machi people have
been asking for since the beginning is
dual boot. being able to install Linux
next to the Windows installation so that
they can still play all their games. And
I just went like, do you know what? I
have more than one computer so when I
play play games, I can just do it on the
PC. It's not a me problem.
>> Yeah,
>> I totally get why a bunch of people
wanted. I'm not heavily inclined to
spend four hours figuring it out. And I
just uh a little while ago went like,
oh, this is exactly the kind of problem
like I don't have to figure it out. Just
made the agents figure it out. So I
kicked off initially the process of just
coming up with a plan. This is a pretty
good big change, right? Like if you [ __ ]
up someone's boot records or you
overwrite their petition criticality
high, which was one of the reasons I
didn't want to engage with it. Secondly,
it's a little finicky if you want uh Lux
encryption on the Linux partition, but
the Linux partition doesn't own the
whole drive. It's a little hairy. I
didn't want to take on the criticality.
I'm like, this is perfect for the kind
of agent stuff. So it started off
basically just having Opus and Codeex
pingpong a plan. Like I'll just I asked
Opus first like come up with a plan for
this it thinks for minutes and minutes
and come up with a good plan and then I
kick it over to Codeex and like critique
the plan and then I had him ping pong
back and forth a couple times and at the
end looking at the plan going like yep
that's a good plan we should totally do
that and I can't wait to kick that one
off and just go yeah now does dual boot
not because I did it but uh thank your
uh your helpful clinkers. That level of
ambition is still something I've yet to
internalize. Like even just that that
like, hey, here are these hunches or
demands, projects that I would like to
do and maybe someday and you could kick
it up on a hunch while you go to lunch.
That is a new world. Which is also one
of the reasons I think a lot of people
are thinking, well, the model continues
to improve, but even if we somehow hit a
wall tomorrow, the bitter lesson is no
longer true. There's actually a limit.
It's 19 trillion tokens. That's how much
they can learn. Not true at all. But if
it was and we had to be stuck with these
models, we would spend the next decade
just getting more and more out of them
learning how to use these tools. You see
this actually with vintage computers. So
the kind of games they were able to make
on the Commodore 64 when that was
released back in 81 to 85 I think was
the main run. I know they made it a
little longer, but then the AmIgga and
other machines came out. Were great
games. I mean, I got interested in games
of the Commodore 64, Yung Fu, and all
that stuff. The stuff they were able to
do 20 years later when someone had just
noodled all the secrets and tweaked the
one MHz processor
>> when they're building games for the old
old
>> Yeah.
>> are so much more technically impressive
because we just know so much more about
the I mean, same thing with the you look
at the PlayStation first games come out
on launch, last games before we go to
PlayStation 2, they look from they're
like from different generations. We
could totally continue to do that with
the models, but we're not going to have
that particular enjoyment because
there's a new model dropping in 3
months. But this is interesting because
if we just run with this thought like of
course we know new new things are going
to come but the point is like we will be
spending so much time learning applying
them building either our internal
systems changing how we build things
taking on new project like if you're an
existing team now that people can do
more work and more ambitious work. How
are you thinking of of the team taking
on more work launching more products?
Are you thinking of of potentially
growing the team or keeping it as is? My
best assessment for our setup is that
the same people can do much more.
>> Let's internalize that. But that's also
enough. Already we were doing enough.
Already we had margin that we could hire
way more if we had enough good ideas for
that. So all this extra productivity
we're getting out of the team allows us
now to do things like P1 and these other
projects that are awesome and they're
going to improve the product faster too.
Of course they are. The old way of
thinking like it's going to take 2
months to deliver a major feature. I
mean that's out the door. Of course
there's going to be rapid acceleration
that's going to filter all the way into
our software methodology process like
shape of was built on two-month cycles.
That doesn't make sense in the same way
at all anymore. We have not fully
rewritten those scripts yet because the
acceleration is still so fast. No
company really has rewritten the scripts
on on all that. When you're shipping
that much faster, you need a way to
control what goes live and measure
whether it's working. This is a good
time to mention our presenting sponsor
stats. Experimentation feature flags for
teams that ship fast. Static build a
unified platform that enables both
experimentation and continuous shipping.
Built-in experimentation means that
every roll out automatically becomes a
learning opportunity with proper
statistical analysis showing you exactly
how features impact your metrics.
Feature flags let you ship continuously
with confidence. And because it's all in
one platform with the same product data,
teams across your organization can
collaborate and make datadriven
decisions. To learn more, head to
stats.com/pragmatic.
With this, let's get back to the shift
about to hit developers. But I still
think software developers are delusional
if they do not think a shift is coming
where before they were the constraint on
how much could be produced and therefore
could command
>> the salaries that flow to the
constraints. If suddenly those
constraints now loosen, especially if we
fast forward a little bit where the
product manager is actually able to
produce changes that can be shipped and
work, things are going to change. I do
actually think if I was going to bet
we've seen peak programmer in terms of
the learned guilt of programmers who
went to either school or spend hours
getting really good at it. we're not
going to need the same number of them to
do the same amount of work. Now, Javon's
paradox where as the price of something
goes down, you get more of it or you get
more demand for it is true, but that
doesn't mean that all programmers are
going to get bailed out by it just
because more software than ever is going
to be produced. That's for sure. By the
way, I think
>> GitHub has gotten a lot of slack or flak
lately.
>> A lot
>> justifiably so. I saw a chart saying
they had a 92% uptime, which sounds
insane. I'm not sure exactly what that
was measuring, but I feel it. I have a
little bit of sympathy in that. I also
think there's some mistakes were made,
but also that the amount of software
that's currently being produced is on a
rocket ship. We are producing as a
civilization globally way more software
than we've ever done before. I mean,
open claw itself, I thought um he said
it was 400,000 lines of code. That used
to take 10 years and 2,000 people. Yeah.
To get to that.
>> Well, not 2,000 in and but yes, it it
took a long time.
>> I mean, a long time, right? Like you
look at uh I think uh the main monolith
at Shopify is 3 million lines of code.
That's 20 years. And if you collectively
sum up all programmers who've worked on
that, probably like 20,000 people. Yeah.
Big shifts are coming right now. Um lots
of software is being produced. I can see
why it's it's creaking a little bit over
there because like the pushes are just
going to accelerate, right? And we
haven't even seen anything yet. If you
look at AI adoption
curves, basically no one's using it.
Like we all in our little bubble in X
are like, oh, everyone's no they're not
like most companies in the world are
just not doing it. Notwithstanding that
like I think uh chatt got to 800 million
users very quickly. Obviously, there's
adoption, but nothing on the scale of
what the companies that are furthest
along are doing and how much they're
accelerating with it. So, I do think it
is correct for the average programmer to
think maybe we've seen the best of the
golden days. Certainly there will be
pressures on price because one thing are
companies like ours that have
essentially unlimited scope to come up
with new features and do more and we can
then plow in all that additional
productivity into just do more. There's
also a lot of companies who just need to
do a thing and if they can do that thing
at a tenth of the cost that's actually
their advantage, right? They just need
to do this thing. It's very neatly
scoped and defined. It's a cost center.
Anywhere where software development is a
cost center, which is actually probably
the majority of software development in
the world,
>> they're going to face these pressures.
>> Yeah. Sounds like if I'm a software
engineer right now and I'm worried about
like well, you know, like just want to
make sure that I'm I'm at a place where
things are going to be better. You want
to be at a place where you want to
either get out of a cost center or
become really valuable there. Obviously,
you know, brush up your skills. And also
I'm wondering if if the shape of
software engineers who will be hired
will be changing cuz if if if I just
look back from like the '9s right like
even if you look at the movies you you
saw the stereotypes they were the nerd
who didn't talk to anyone but they knew
how to code they knew how to do assembly
and then we went in the 2000s it was
still based on languages and over time I
think in the 2010s startups started to
not hire for languages but just hire for
algorithms because you could learn the
stuff and now I'm seeing companies uh
some of the the the latest VC funded
companies have for product engineers
where they they're actually asking for
like empathy communication on top of
like it's kind of a given that you you
know how to code or whatever. So I
wonder if I'm just looking at just just
this curve, right? If I'm just painting
it up like you're starting to get people
Oh, and and the developers I I meet at
all these companies, they're all really
pleasant. They're all just very
communicative, very oh and they talk
with customers, most of them just it's
it's not even a drag. It's like and more
and more of them love doing it. That's
the constraint value. Now the constraint
value is figuring out what should we
build, how should it be built, which
customers should we be talking to, where
should we be focusing. It's product
management. It's so funny for me too
because historically I've not
necessarily had the highest esteem for
product management as a function. I
thought there was a lot of [ __ ] and
I thought it was a lot of people who
maybe didn't do as much right and one of
the reason was that they couldn't
because the constraint resource was the
implementation was the product manager
could find out that they want to do
something I want to do this feature and
then they had to wait four weeks for
some very expensive programmers to make
that reality happen and in those four
weeks I mean I guess they could go talk
to some they were underutilized they
were not the constraint right they the
constraint was on the implementation
that absolutely absolutely is going to
switch
>> and now pure implementation
is going to be solved at some point. I
I'm not claiming it is right now and
anyone who is have not tried to just
deploy bipoded stuff with no review to
major code bases but as the lesson of
last summer on Lex I'm not going to put
my heart on the block and saying that's
not going to happen before next summer
>> again this is just like common sense but
implementation one implementation will
be solved for for a general use case for
the edge cases it will take longer and
for some cases it will not make sense
same thing as I know self-driving is
fine for like these size of cars but for
like trucks it'll either take longer or
if you're specializ you do but the point
is like there will be pockets where but
those pockets will be smaller. Yes, I do
think the stereotype of I just want to
sit and code. You have to be John Karmic
levels of good to retain that privilege
to just I just want to sit and code.
>> And even John Karmak is also super AI
appeal and lead.
>> Well, but also like he he also saw some
trends that he could do like for example
like just like you know the type of
games that people would buy, right? Like
he needed to have some business skills
or just surrounded by people who did
that. Totally, totally, totally.
>> But like you you need to literally be
the very best. And not just the very
best, but you need to be better than the
agents, right? Like for you to get the
privilege to just be an implementer, you
have to be better than what's available
off the shelf from from agents. So, who
are the very best? And you're a good
person to ask because whenever you
advertise a position, and this was even
well before AI, I remember that you you
put out a a a job for both software
engineer and a designer. And actually I
want I'm I want to interview your
designer who you hired and because uh
you published the salary which is a San
Francisco salary. You put the exact
number you can check it for it. You have
a social media presence so it's kind of
go go goes wide and you get a lot of
applications and you do a pretty good
job as as I understand you try to be
very fair. You put a lot of effort into
it. So, what did it take to get hired at
37 signals? Because now you are trying
to hire some of the best and based off
of this, what advice do you give to
people who are like, okay, I want to be
the best in in this age right now.
>> Incredibly good question. No one has
figured out we haven't cracked it. And I
say that as someone who have run an
organization where we we must have
looked at tens of thousands of now, of
course, if you're running Google, you've
looked at millions, but we've looked at
tens of thousands of candidates. The
number of candidates we've hired is
quite small. I mean total number of
programmers that's been through 37
signals over its entire lifespan. What's
that going to be like I don't know 100
150 at the most? I haven't even
>> How big is your team right now is?
>> Uh we're 60 people at the entire company
and we are what is that going to be like
20 programmers something like that.
>> Yeah, that's probably about right.
>> Oh, so so who what is the other other 40
folks?
>> Uh we have designers
>> uh probably like 10 of those.
>> Wow. Wow. And then we have customer
support which is at 14. Then we have a
bunch of support functions, HR, finance,
and then we have operations. Operations
is quite large. We have 10 folks
managing all our servers. And yeah,
that's about it. But yeah, I probably
it's probably about 100 people in total
that I've worked with uh or employed at
the company's programmers
>> out of tens of thousands
>> we've looked at. And even all those
hires did not pan out in the long term.
Like I'd actually say I think I looked
at this recently. Our batting average at
best I think is slightly better than
50/50.
So half of even those hires
>> you go through all of because you have a
really long and thorough process. You
you you put in a lot of effort, right?
>> No one has figured out just to hire with
such efficiency that they don't make
mistakes. There's a great paper that
Google published quite a long time ago
now where they tried it all sorts of
different hypothesis. Well, can we
predict employee outcomes on the basis
of Ivory League education background on
GPA on all of these things? And the
conclusion was basically like we know
nothing.
>> We can't predict it on any of these
things. We can't predict it on lead
code. We can't predict it on any of
these metrics.
What I'd say is I've clearly been
spoiled by working with some very good
people, not just at my company, but in
open source in general.
>> Yeah. Oh, yeah.
>> And therefore, I've ended up with
occasionally a twisted perspective of
what the average programmer is capable
of. And when we do hiring rounds, I am
sometimes, well, not sometimes, I mean,
every time, I'm kind of surprised how
poor the majority of the submissions
are, how little effort is put into
being presentable. And that can sound
really boomery very quickly, but it's
also just the reality of trying to get a
job. Like, you got to stand out. And I
understand that that's uncomfortable,
right? like who wants to look at this as
like well my the odds are kind of
against me but it's also a trap to
actually fall into thinking of this in
terms of odds because what I've seen the
miscalculation happened time and again
is people go like okay so you have a
thousand applicants there's only one who
gets the job or maybe two who gets the
job so that 0.1% chance no it's not not
at all with that math you had 0% chance
>> yes
>> zero and the very
They probably had a 10% chance, 20%, 30%
chance. It is not equal distributed. It
is not a lottery. We don't just like
pick a thing out and be like, "Oh, it's
going to be this person because they
happen to be the one drawn from the
bunch." Not at all. We discard off the
bat probably at least half the
applications. Maybe it's twothirds just
because they're either not addressing
the job directly, they are not following
the instructions in the relatively clear
spoken written openings that we have,
right? they're obviously not right for
it or or whatever or we get some other
smells. Then there's like perhaps a
third left and then we start looking at
some of the submissions. Then we narrow
it down historically to a pool of around
20 people that we give a at home test.
The at home test is wonderful. Some
people hate it. They feel like it's free
labor. I'm like, what the [ __ ] are you
talking about? I'm not going to use your
submission to a code test. What? I'm
going to deploy it to production. How do
you think we came up with that code test
because it already exists in the system?
I say that a little harshly. I also get
the sympathy of like I don't want to put
six hours into making a test if it's not
going to go anywhere. Okay, I get it.
But there's no way around it because if
you have it in your head that you just
send in a resume, someone's going to
call you up on the phone, have a
30-minute conversation with you and go,
you've hired sir. I don't know if that
ever existed, but certainly does not
exist today. It never existed in the
lifetime I've been in this. Well, the
only time it exists, right, is
>> through a very warm referral where
correct
>> where you're starting a typing if you're
skipping the whole pipeline.
>> And when you skip the whole pipeline, it
typically only happens at the very
beginning of a company when you're
founding a company and often it goes
both ways where it's very risky and then
you say like this buddy of mine, I work
with this person for two years straight.
I would like trust them with my eyes
closed. So that's actually the black
pill on the whole hiring process. If we
look at the long-term success rates, we
have had more long-term employees from
I've worked with this person for 2
years, we should hire them than we have
from the open calls. It is actually
exceptionally difficult
has been for us to find the kind of
programmer who thrives in our
environment from open call. It has
happened. We have hired people that way
and I continue to want to believe even
if the odds seem insanely long when you
start doing the math of like oh my god
we've looked at tens of thousands and
how many then got hired and how many
then didn't work out like Jesus there's
only like a handful left from starting
with that that that's kind of
blackmailing but then hiring directly on
the base of warm referral as you call it
um has worked very well and that the hit
rate there is really high but how does
that help anyone right like that's not a
very actionable advice except that's to
say Get as good as you can get and put
in as much effort as you can and work
with someone because I want to say that
as a counter. Some people have this
notion in their head that if they work
at a place they consider shitty, they
shouldn't try.
You're shooting your own feet, buddy. If
you show up at the shitty place of work,
and we can even be objectively in unison
about that, that it is a shitty place of
work, and you then go like, "Well, I
should just try to skirt. I should just
try to goof off. I should just try to
read X or Reddit all day, right?
Everyone else you work with, they're
going to watch that. You know where that
warm refo is going to come from? It's
going to come from someone who worked
with someone else at a shitty job, but
identified that that individual still
showed up and did as best as they could
to learn, to ship, to do all of this
stuff. There is no shortcut here. You
simply just have to be good. And you
will not get good if you do not
practice. And if you think your place of
employment is not worthy of your best,
you're cheating yourself.
>> If you're not helping, even if it's a
shitty place, if you're not helping that
place get better, why would a great
place hire you who only hires people to
to further raise the bar?
>> This is total cope. And it's cope both
on the side of I work at a shitty place
if I don't want to put things in. You
could be annoyed. I'm not telling you
you have to love your boss. I'd actually
say the majority of people I used to
work for, I didn't have the warmest
feelings about them. I still tried
really hard for my own edification, for
my own education, for my own sense of
I'm the kind of person who shows up and
does a good job just that I will be
ready when the opportunity arrives when
all my talents are needed and all my
skills are honed. Right. Well, well, was
this not how you ended up at 37 Signals
where it was just a contract job or
something and you know like on a
contract job you have no ownership and
correct but you showed up and
>> correct and Jason ended up realizing
>> okay this uh punk better get some equity
otherwise he's out the door now that's a
siminal story and you shouldn't
extrapolate everything from that I mean
all founder stories by the way are
siminal stories in that regard but the
fundamental principle is still the same
show up do as good as you can learn
more. There also was to my
chagrin to some extent. I perhaps
contributed it to it a bit for a while,
which was this notion that you can be a
great programmer and not really like
programming. That you don't have to ever
care about programming outside working
hours. Was was this what you thought of
or like
>> Well, I thought of it mistakenly because
I was pushing back on the overwork
100hour week, 120 hour week maniacal
obsession, which by the way never was my
experience. We did not start base camp
that way. We have worked on a 40hour
week rolling average over those 25
years. But also, as I said at the very
beginning, I really like computers. So,
I play with computers in my free time. I
look at computer things in my free time.
It's not work in the sense that I'm
whatever shipping features to basec camp
customers like just 247. That's not what
it is. But I am playing with computers.
I am looking at new things. I am
exploring new systems and whatever. And
I think there was for a while in the
2010s a misconception that you didn't
have to do any of those things. you
could just show up and do your work and
you would be so soughta because
programming was such a valuable activity
and there were so few people who could
do it that they'd take anyone even
people who barely gave a [ __ ] and I
think that's over if it ever was true
and I think it was true
>> the boot camps were the perfect uh like
catalyst or or like they were the canary
when
>> which also by the way is how the economy
is supposed to function when salaries
are really high it means that there's
not enough supply of labor Therefore, we
should get labor into the pool.
>> Exactly.
>> And so, I'm not I don't even have any
qualms about internet. I'm just saying
like that's over.
>> No, I I think looking, you know, we're
talking about like is it is the golden
age of the programmer? Have you passed
peep programmer? And I wonder if peep
programmer really meant that almost
anyone who wanted to get into the
industry and was willing to put in some
effort, few months or maybe a few years
could do it. You could learn how to
code. You could go to either college or
to a boot camp or put in the hours and
you could get hired at a place because
the interviews were the references were
not needed. We we didn't check and I
it's probably coming to an end. You do
need references. You more I think more
and more companies will be doing
reference checks as part of our thing
and it's not just going to be have you
worked there like would you I I've had
these calls from like data bricks is is
famous for reference cards. They don't
only check for references. They drill
you not just would you work with this
person again, how what were their
weaknesses,
>> right?
>> Where would you hire them, etc., etc.
And
>> no, I understand it. The weird thing is
peak programmer sounds like this is
something that affects all programmers.
It does not. The best programmers are
not even the best as in like it's 10
people around the world. really good
programmers are currently more valuable
than ever because they're the ones who
are able to get the most out of the AI
acceleration. And this was the kicker
for me in changing my perspective on
this is that I've also found and maybe
it's not universally true, but certainly
within 37 signals in my own experience,
I'm enjoying my time as a programmer
more than any time since early 2000s
when I just discovered Ruby. This has
the I just discovered Ruby feel to it
that it is so satisfying to be able to
move this fast on so many levels at the
same time to be able to explore the P1s
to be able to think about dual booting
omachi to do all of that stuff that the
work itself has gotten vastly more
enjoyable and I've seen the same thing
for the most AI forward programmers that
we have maybe also have some of these
anxieties but they're kind of pushed to
the side just out of sheer enjoyment
working with the new capacities. So
there is a bifocation here where we
should all feel like well we don't know
what's going on and for some people
that's going to produce some degree of
anxiety. I understand that especially
when it's your livelihood and you're
like well I'd also like to be able to
pay for my kids college in seven years.
What does that look like? I get it.
You're not going to be able to manifest
that anxiety into anything productive
unless you just plow it into leaning in.
Right? Because if you just sit and spin
around, try to think about what the
world's going to look like seven years
from now, you're wasting your time. So
that's the only path. The only path is
to either get excited about this, which
I don't even think takes that much
effort. As we said, if you sit down with
these models, you pull out one of your
hobby projects from the closet
>> that you never finished,
>> that you never finished, and you just
give it a try, I don't see how you
really like computers and not find that
experiment enjoyable. And I I've seen
this with with people who are getting
into it. Kent Beck is such a great
example. He's been programmer 52 years
and he is saying like he he loves doing
it and he found this balance between
using the agents to build something
ambitious that he always wanted to b
he's building his small talk server
which which used to take forever and now
it's it's getting closer and it's still
taking a long time and then in between
he's chilling at his he has his house on
on the lake and he just goes and like
just looks at the birds for two hours
and then gets back to it. It's
beautiful. Kent is, by the way, one of
my all-time heroes. This was right when
I got started in programming right when
I before I was picking up uh Ruby, I saw
Kent speak at a Danish conference in
2001 on stage and I was completely
mesmerized by his command of both the
material, how bold he was and how great
of a speaker he was. And this was after
having read Extreme Programming and many
of these other things. Small Talk Best
Practices is my number one
recommendation for any programmer who
want to learn the nitty-gritty of how to
structure a method and a class and the
rest of it. Small Talk Best Practices,
which is Kent's book from 95, I think,
or 96, is to this day my favorite book
of all time on tactical programming
uh patterns. So, it's wonderful to hear
him being agent pilt while also enjoying
the birds. I mean, I try to do that,
too. And this is actually there's a bit
of attention right now is that most of
the people I find who are allin, they're
working harder than they ever have. And
I've seen that with myself now too. When
you can be this effective and impactful
on an hour of supervision of these
agents, it's really intoxicating. If you
have an active uh dopamine loop up there
that gets triggered when something is
shipped, it is just hyperactive right
now. And I need to go, do you know what?
This is not like a limited sale. like AI
is going to be here next month and the
months after that. Like I cannot just
operate as though it is a limited sale
and I need to get all the dopamine in
harvested within the next two weeks.
That I actually think is the main
challenge right now for the people who
are furthest along and most pled on it
is like remember that this is as bad as
they're ever going to be as the cliche
goes, right? You damn well better find a
way not to get consumed entirely about
it as exciting as it is. And and then
yeah, there there's this consuming is is
is a big deal. Like with Steve Yaggi, he
was he looks a bit more drained than
like you can see it on the video, but he
he has he's honest like he's he's being
pulled into this. He's doing he has
friends who are and when when you're on
the edge, you're there. You've clearly
been AI pill, but how are you finding of
keeping a balance of like all right,
stepping away, you know, like I I know
you've I think you previously talked
about the importance of sleep.
Apparently you don't have an alarm.
>> Correct. I don't use an alarm, although
my wife now does because the kids need
to go to school on a regular basis. But
yeah, for me, eight hours a night is the
best investment you can make in your own
cognitive capacity. So, I just am
reminded every single time I do not get
eight hours that it is such a poor
trade. If you go from the eight to the
six, I go like, well, I'm going to be
awake for in that case 18 hours. What is
the drag I'm gonna carry for all those
18 hours for getting one more hour, two
more hours by cutting back on the sleep?
It is such a bad piece of math. It makes
no sense. Now, occasionally it's
involuntary. I have actually had,
especially around this AI stuff, I've
had a couple of times, very rare, I can
count on two hands the number of times
where I've been sleepless, like the ra
the brain racing a little too much.
That's not typical for me and it's still
not typical. But I have had a couple of
them, right? So, I get where some of
that excitement comes from. But I'd also
say the last thing you should trade is
sleep and then you should not trade your
health. You should not try to save the 3
hours a week of working out to do more
agent work. That's a very poor trade.
Keep in good condition. like there's
nothing this can be more important if
you want to keep like sharp up there
that like the rest of the system is
operating if not at peak capacities than
at uh at a good sustainable level right
and I do think there are some
individuals right now who are at fear of
running ragged
>> on something that we're going to be
dealing with for like slow down buddy
like it's not again a limited sale the
next 10 years we're going to see more
and more it's going to get crazier and
crazier so don't squander your health
don't squander your sleep don't squander
your diet in the service of anything
because even on the short term, it does
not work. You cannot get more productive
within 3 weeks, let's say, by trying to
cut back two or three hours of sleep
every night and then think there's
anything coherent left after 3 weeks.
You will be a hot mess. So, let's close.
We talked about the stuff that we don't
know. A lot of things we don't know, but
let's close with what you do know. So
you you could have retired a long time
ago and just you know kick back and and
like listen to birds. What is it that
keeps you doing keeps you building
keeping getting up every day and before
AI you would open your terminal I think
you you shared like like you would go
and and write now you're doing with
agents like what drives you and and and
looking ahead like what what are things
you're excited about?
>> My drive continues to be a deep love of
computers. This is simply the best way,
the most fun way to spend my time. I
could spend my time on a lot of things.
I do spend my time on a lot of things. I
don't just do computers. I drive race
cars. I take lots of time up. I have
three kids. We enjoy all of that stuff.
But if I'm going to fill eight hours
every day with an activity, my best bet
is computers. And it has been so since I
was literally 5 years old. Whether it's
video games or what now feels a little
bit like a video game actually
instrumenting all these agents and uh
playing a little bit of Starcraft with
moving them around and
>> Toro.
>> Yes, exactly. So, I just really like
computers. So, whether I need to do so
for economic reasons or not, I will
continue to play with computers, see
what makes them tick and make things. I
think that's the other big misconception
that some people have about wealth is
that they conceive of it as some sort of
checkpoint. Like once you've made it,
then you can just kick back in leisure
as though that was happiness. We simply
have a hundred years of psychological
studies telling us no, that's misery. If
you have all the time in the world and
no purpose, no mission,
leisure is not going to cut it. It's not
going to be fulfilling way. And this
should be obvious by example of
literally every entrepreneur who sells
their business. They sit on the beach
for three weeks and then they're back
into the game, right? Because this is
actually not just something they do in
pursuit of a goal. It's the goal itself.
It is the mission itself. It is the
satisfaction. It is the affirmation of
being a human that I'm not just a blob
laying around. I am a useful individual
who put my skills to the best use
possible. So, I'm going to continue to
do that. And I'm going to continue to do
it whether I'm sitting typing at the
keyboard, whether I'm instrumenting
these agents, whether they're teaching
me, however which way it is, I want to
play with computers, I'm going continue
to do that. And then even more
specifically after the last three
months, I'm leaning in hard now with
agent accessibility. For example, this
is what I've been doing the last few
weeks. We've been working on the new
CLI, which also taught me like we're not
quite at AGI yet, right? You think like,
well, just ask your agent to make a CLI.
It will, but like it's not quite there,
right? like I want it to be just right
and the agents still need a little bit
of help. I'm very happy to provide that
help to these agents and we'll release a
great CLI for Base Camp very very
shortly. Maybe by the time this is out
it'll probably be out and for the rest
of them too and I want to lean into all
of this. How can we use this as much as
we possibly can and then right now I'm
also just an incredibly cur curious
person. I wake up every morning I have a
new ritual which is not to pull my phone
up and start hopping on X. like right
when I wake up. I don't think actually
that is great. But it takes a tremendous
willpower to not do so because I'm just
so curious about what happened. There's
so much happening right now. I want to
know. I want to know. I want to be
enjoying it. Be a part of it. So I don't
foresee that ending. I don't foresee a
love of computers evaporating. In fact,
if anything, right now I'm seeing like a
a flourishing of it. I'm liking
computers more than I did five years
ago. And that's amazing. Amazing, David.
This was awesome. Thanks. Thanks a
bunch.
>> All right. Thanks for having me. This is
really great.
>> This was a fascinating conversation and
I love the energy that David has. I hope
some of this energy that is obvious in
person also came across to you. I really
appreciated that David was open that his
stance did not change about AI because
his philosophy changed. It's just that
the tools became good enough to do
useful stuff. AI for autocomplete was
annoying for experienced developers. AI
agent that can produce pretty good
working code by themselves on the other
hand are now pretty useful. And yet
David kept coming back to taste,
judgment, and craft. He wasn't just
saying just let the model write
whatever. It's the opposite. He has a
very high quality bar and he wants the
output to be code that he would actually
be proud to merge. It feels like AI
might make good judgment even more
valuable than before. I also really
liked how David thinks about the
importance of design. At 37 Signals,
designers help figure out what should be
built, how it should work, and
increasingly even decide how it gets
implemented. I wonder if 37 signals is a
step ahead of the industry in thinking
about designers a bit like developers as
well and developers a bit like designers
as well. Finally, I found David's take
that we might have hit peak software
engineer an interesting argument. David
thinks we'll produce more software than
ever. But his observation is that we
might be nearing the end of the time
when developers could command high
compensation simply because they were
the bottleneck. My two cents is that
there will surely be high demand for
professionals who can build profitable
software. But this will mean software
engineers who are not only good at
coding or using AI to generate code, but
can oversee building complex systems
have taste and business sense as well.

David Heinemeier Hansson (DHH), creator of Ruby on Rails and CTO of 37signals, discusses his transition from an AI skeptic to an "agent-first" software builder. He explores how modern agent harnesses like OpenCode and Claude Opus have transformed his development workflow into a "mech suit" for productivity, allowing for massive efficiency gains in tasks like PR reviews and performance optimization. DHH also details the unique culture at 37signals where designers act as product managers and implementers, and he shares his perspective on the industry hitting "Peak Programmer," where the value of software engineers shifts from pure implementation to high-level judgment, taste, and craft.
