AI made it cheap to generate product ideas and ship a beautiful demo of any of them. It didn't make it any cheaper to turn one into a real spec — the kind that answers what this actually does, who it's for, what happens at the edges, and what we're cutting. The bottleneck used to be R&D throughput. Now it sits with whoever has to take the demo and do the unglamorous work of turning it into something an engineering team can build. #productmanagement
