I really agree with a lot of this but also think it may be hitting a bit too hard. It may be most applicable to engineer founders.

My anecdote is that, after a few stings with non-technical founders, a doc etc will not improve the chances to reach PMF and prototypes that they can understand can improve the chance.

Outside of the startup context, I have also seen prototypes (hand written way back when that was a thing) resonate with FAANG directors much more than brainstorming.

I am very much for not just vibe it, and the biggest risk of prototypes is they lend to just directly launching broken systems to production. But I think this is a different topic than reaching PMF.
