"Permission to suck" made me think of something even more fundamental that's relevant to the AI art conversation, and often forgotten; that the best art, the most creative work, comes when you're working around constraints. Those could be the constraints of a medium, if you're chiseling in stone and need to make certain trade-offs; or they could be monetary constraints (you can't afford a cast of 40,000 extras for a war movie, so you turn your focus on the intense local experience of a few characters). In a "necessity is the mother of invention" kind of way, having limitations forces you to think more carefully about every move, and that kind of thought is what can make something a small masterpiece instead of a large sloppy shitshow.
Given an unlimited budget, most directors will lose their heads and do terrible things, even with a good script. Having no limits brings out the worst impulses in any creative endeavor. If "AI filmmaking" comes to stand in for "unlimited budget", then I think the trend in the future will be toward smaller, more human-scale art, because artists will find constraints to work within as a means to focus.
Maybe I'm not saying this as well as I could.
