But at least artists have some agency, all that stuff that they ingested goes through them and are somewhat limited by human hardware. Very little is original indeed but that percentage may as well go down even more as more and more AI generated soup unleashed on the world.
What about artists that used random generators in their art? Jackson Pollock used to randomly splatter paint on canvases and when some random pattern struck his fancy he went with it. That's not all that different from picking the pictures you like from a Stable Diffusion prompt and then further honing them with inpainting, image-to-image and so on.
