Discussions of AI-generated art that try to cut the tech off at the knees by invoking copyright regarding training the generators on artists' work without their consent are fine, but short-sighted and won't stop the economic shift.
If these tools prove valuable for generating sufficiently-novel, sufficiently-controllable input, advertising companies and entertainment companies *will* pay fifty artists for their labor to generate the seed data to create fifty million images.
These technologies, should they prove viable, will become a permanent tool in the toolbox.
