tl;dr: At Rails World 2026, DHH used his keynote to announce he's "retired from professional programming," is rewriting Hey as native apps with a Rust backend (chosen because it's LLM-friendly, not human-friendly), and claims hand-written code will be obsolete for nearly all programmers by December. The author criticizes the talk for offering no actual vision for Rails' future, relying on flattery instead of strategy, and making incoherent productivity claims (like comparing 150k lines of LLM-generated Rust to 30k lines of hand-written Ruby). The core complaint: the creator of Rails moved a flagship app off Rails and said nothing meaningful to Rails developers.
