Text to speech is pretty much a solved question at this point, but nobody said it will replace voice actors, nor did it. It conquered TikTok, I'll give you that, but that's barely an accomplishment.
For me AI art is the same thing. It can give you serviceable material in a very fast time, but that's it. It's a Big Mac of the art industry. It's not gonna kill artists like how McDonald's didn't kill restaurants or even rival fast food chains or gourmet hamburger shops, because the only thing redeemable in AI art is you get variations of well-known styles (putting "trending on ArtStation" in the prompt to make it look good is a thing. let that sink in).
