Microsoft CPO: If you aren't prototyping with AI, you're doing it wrong (Aparna Chennapragada)
Microsoft's product chief makes the sharpest case yet that prompt-built prototypes have replaced specs.
Watch on YouTube youtube.com →Because a working prototype beats a pitch deck and a job posting: in an afternoon you can put a clickable version of your idea in front of real users, sharpen your spec, and find out what is worth building before spending a rupee on salaries. A quarter of recent YC batches ship codebases that are mostly AI-generated, and product leaders now treat prompt-built prototypes as the new PRD. A designer is still worth hiring, but later, when you have signal and need craft and consistency, not to produce your first draft.
A quick orientation. The real value is below: resources worth your time, from people who've actually done it.
