💻 Ruby on Rails Creator Completely Abandoned Manual Programming

David Heinemeier Hansson (DHH) stated at the Rails World 2026 keynote (September 23, Austin) that he has not written a single line of code by hand since March 2026 — after a 25-year career. In his words, “English is the best programming language, better than Ruby,” and manual code is “no longer an economically productive activity.”

🌍 The most prominent AI-coding skeptic is legitimizing agentic development: at 37signals, manual code has become the exception, and all products will get a CLI for AI agents.

👤 DHH himself works with two agents in the terminal (Gemini 2.5 for speed, Claude Opus for complex tasks) and reviews diffs in NeoVim and Lazygit. There are no strict metrics for such workflows yet — you will have to check them yourself.
