AI Summary

At RailsConf last week, David Heinemeier Hansson — the creator of Ruby on Rails — stood on stage and told his community that he's done writing Ruby. His argument: if you're not reading the code anyway, why not write everything in something that's super fast, like Rust? The Rails subreddit responded about as well as you'd expect. "DHH straight up lying," "DHH is a certified dumbass," "get DHH out of rails" — the backlash was immediate and loud.
But here's the thing: when you actually watch the keynote, it's harder to dismiss. DHH's core claim is that the abstractions Rails provided — the conventions, the readability, the developer ergonomics — mattered when humans were reading every line. Now that AI is writing and reviewing most code, why not use a language that compiles fast and runs fast? He pointed to Shopify's move away from React Native as evidence that native apps are becoming easier to build, making web-first frameworks less necessary. It's not that we're done building software; it's that the layer of abstraction Rails provided may no longer be the right one.

Scott, Wes, and CJ ask whether Ruby on Rails is really dead (and whether Rust is just Rails you don't have to read), then dig into Meta's new Muse agent, which is free, comes with its own VM, and is already reading messages nobody asked it to. Plus: upm, a tiny TypeScript npm replacement, Opus 5.5 moonlighting as a motion designer, Tart VMs on Apple Silicon, and a foundry for gloriously bad web fonts.
