One of the major concerns with prototyping, at least in my experience and based on the general vibe I've felt from others over the years, is that clients will generally do some variation of "You have a working prototype? So how many days until it is prod ready? No more than a few weeks, right?" and that will be their expectation. AI makes prototyping easier, but makes this specific drawback much worse. Expectations are going to be misaligned, leading to many disappointments, and likely some number of developers taking undue negative outcomes. I'm not even sure if it will normalize to reasonable expectations, given that this tension never seemed resolved even before AI was in the mix.
