As a programmer and seeing the work (and damage) AI does to my field, i feel i might be a little biased too, but all the same i feel like i have a good insight in what you can and cannot use an AI for. Its very very very good at low skill menial tasks. For my work this would be anything a junior dev would be doing, the glorified boilerplate code, the milliont re-implementation of a common libary, the copy paste JSON entries, the... i could go on really. But as soon you demand more of it, you're spending more time fixing its code than you would have spent just writing it yourself. So i figure, if you're trying to make invidual images and dress up a game with them, that might work quite well. With a fair bit of work you can get it to look somewhat consistent too. I've seen VNs pull it off. But if you're trying to make block textures, that tile, rotate etc without causing seams or looking bad at a distance... I fear you might be shit out of luck trying to use AI. For how simple these textures often look, there are a lot of considerations and demands upon it, that make them work... That AI currently (and maybe forever) is incapable of understanding.
