@sfruby.com (#sfruby) — Day 1 (Part 2): Talks changing how we think about Ruby 🤯
If Part 1 was about views, performance, and AI in monoliths, Part 2 dives into something even deeper: how languages evolve, how we design systems, and how AI fits into Ruby’s future

🎙️ José Valim #sfruby — “Navigating Language Evolution in the AI Era”
- If AI generates the boilerplate, frameworks must focus on higher-order abstractions
“AI doesn’t replace language design — it reshapes what languages are for.”

🎙️ Dave Thomas #sfruby — “Start Writing Ruby (Stop Using Classes)”
Dave asked a beautifully uncomfortable question: Do we reach for classes out of habit rather than necessity?
- Ruby is about objects, not mandatory hierarchies
“Stop reaching for a class when an object with a job will do.”

🎙️ @marcoroth.dev — “Herb -> ReActionView”
A fresh vision for Rails views: modern, reactive, but still unmistakably Rails.
- Rails should feel modern without becoming a JS framework
“I don’t want Rails developers to learn a whole new mental model just to build views.”

An invitation to treat code as a space for exploration, not just execution.

Not AI as a copilot, but AI as a teammate that understands your Rails app’s structure.

🔥 Day 1 of SF Ruby Conference felt like a crash course in Ruby’s future — the view layer, performance, modularity, and the emerging role of AI inside real-world Rails apps. With two tracks in parallel, I could only attend part of the lineup
