React with a clap to Robby on his keynote performance, he rehearsed all summer!
Don't say that is AI, maybe (or not) he presented his dance at the Closing Party
I don’t feel like my keynote got the attention it deserved. @dhh is a tough act to follow.
I rehearsed this all summer! #railsworld

All Rails World 2026 talks now online!
Last week more than 1,000 developers gathered in Austin to hear talks from 27 speakers. While all four keynotes got everyone talking about AI, this year’s talks covered a good balance of what's new in Rails and how Rails developers are putting AI to work: from harnesses to Herb, Active Search to HotCell, generators to Lexxy, and so much in between.
If you got caught in the hallway track, or couldn't make it to Austin, catch up on what you missed here: youtube.com/playlist?list=PL…

In this day one closing keynote from #RailsWorld 2026, @robbyrussell (@planetargon) talks about the "local workshop" every mature Rails app builds on top of the framework: the patterns, shortcuts, workarounds and oral traditions that teams quietly learn to compensate for, and that AI coding agents are now tripping over.
Drawing on years of experience, Robby agrees that while producing code has gotten cheaper, deciding what belongs, what can be trusted and what should change still takes human judgment.

Joel made one of the best talks at #railsworld. When the video come out, update yourself with it.
Here are the slides for yesterday's #RailsWorld talk on applying the principles of harness engineering to raise the floor on the quality of generated Rails code

Replying to @nateberkopec
You are right but it also feels short-sighted? You have the most powerful tool you ever had, you have become a 1000x maker, and you can't think of how to make your stack 10x better?
Yes, Rust is fast, the type system catches bugs, but there is so much beyond it.
* Why not make Ruby 10x faster?
* Why not make Ruby (and therefore Rails) really great at concurrency?
* Why not add a banging type system to Ruby that can provide guarantees beyond Rust?
* Why not embed SQLite3 into Rails with a replication protocol so you can really compress the stack beyond a single server?
* How to preemptively fix most bugs from the most critical parts of Rails, such as database pools?
Yes, who cares about ActiveSearch, but there are so many ways we can fundamentally improve our stacks that go beyond asking the agent to just crap out code. Phoenix is still the only framework that ships with presence, because it turns out it is deceptively a hard problem to solve correctly, but somehow all issues are solved?
I understand some folks have no interest in doing any of the above, and that's fine, but then at least pass the baton to the people who want to do exactly that.
PS: I say all of this with love ❤️

All you Rails Cowboys, make sure you get your behinds to the Ruby Sheriff's Office to get your Passport stamped.
Those that don't yet have one, you're going to have a really pleasant and rather unique surprise.
