Stop Writing PRDs. The Interface Just Changed.
AI keeps generating PRDs that look right but fall apart in implementation. The problem isn’t AI — it’s the interface. PRDs were designed for human developers who fill gaps with imagination. AI doesn’t imagine; it executes. When the consumer of your requirements shifts from human to machine, the document format must shift from PRD to SPEC. One product manager finished five days of work in a single morning using this approach. The real shift: expression-layer skills are now commoditized. Judgment is the only moat left.
