>ongoing training of even-more-interesting generative AI depends on the ongoing labor of artists. What does that mean? That you need artist to produce "even-more-interesting" art to train new iterations of generative AI? Could you point out some of these superfresh new art artist are doing that are completely different than things already done to exhaustion in the 1970s (other than anime)?

I don't think you need artists for that anymore. Certainly you don't need them for commercial purposes. If they are going to survive as an artist professionally, it will be because of the people that refuse to use AI art for whatever reason, but I don't see how that won't be short lived in the market.

Artists will survive, not professionally, but because they are doing it for the arts sake, even if that doesn't offer them any financial reward.
