AI has open a real big can of worms.
Frankly, I see AI training on publicly available images to learn a style which it will then reproduce similar to the problem of game clones.
Imagine spending months/years making a game, coming up with the concept and gameplay, tuning the gameplay, … then after release cloners makes a nigh exact copy with slight changes in artwork/text and sell it for 10% of what you are selling - which they can since they put in only a fraction of the effort - and there is nothing you can do about it since gameplay isn’t copyrightable.
Same thing here IMHO. Not an AI specific problem but AI takes “no effort” when replicating an artist’s style vs a human who at least has to practice and learn the style.
