AI is good to use for translations, learning (though it's still worth double-checking), or solving code problems (for example, finding bugs). Something like advanced searching tool.
Already now, a large part of mobile games use AI to generate crappy ads, watching which literally kills brain cells.
They use it for generating character avatars and other small stuff, like boxes, items, and so on.
For the rest, to get something at least adequate, you need to use a base (reference), otherwise the results will be quite meager.
95% of the games that are on this site and have AI visuals are too similar to each other (and all of them use the same engine, which only enhances this effect). It's like you're playing the same game from the same artist\developer. At the same time, AI has a hard time with complex angles, so mostly it's simple poses.
The bar for artists has certainly risen, but often in job offers, a point "knowledge of AI" just appears, otherwise it's a matter of practice. Same for programmer without experience, and AI knowledge is also required.
In general, of course, I could be wrong, because I don't use AI in my project(only for translate corrections), but just try different services in my free time.
