The messaging from the anti-generative-AI people is very confused and self-contradictory. They have legitimate concerns, but when the people who say "AI art is trash, it's not even art" also say "AI art is stealing our jobs"...what?
I think the "AI art is trash" part is wrong. And it's just a matter of time before its shortcomings (aesthetic consistency, ability to express complexity etc) are overcome.
The push against developing the technology is misdirected effort, as it always is with liberals. It's just delaying the inevitable. Collective effort should be aimed at affecting who has control of the technology, so that the bourgeoisie can't use it to impoverish artists even more than they already have. But that understanding is never going to take root in the West because the working class there have been generationally groomed by their bourgeois masters to be slave-brained forever losers.
