Simon Willison shared Mo Bitar's viral quote about Ralph Loops — the autonomous agent iteration pattern formalized by Boris Cherny (Anthropic, Head of Claude Code). The pattern has spawned multiple implementations including Vercel's ralph-loop-agent and snarktank/ralph. Boris Cherny states giving Claude a verification loop increases quality 2-3x. The concept is crossing from developer circles into executive awareness, suggesting a new category of autonomous coding workflows.
