100% AI art is only useful for replacing stock images and clip art. All the low effort stuff. MS paint memes might get replaced by ai stuff but I doubt that.
Using AI in conjunction with human made artwork, as another tool at the artists disposal, is where it can be useful. Theres all sorts of AI powered postprocessing thats been around for a while. But you could also do draw a spaceship and have AI generate a star field background for you.
Obviously, Capital will take a while to figure this out. It will attempt to use AI to solve its highest priorities first. Replacing all artists and scamming old people are more important than making good art.
