While that is true, just because it's AI generated doesn't really wash away any marginal effect it has on children victimized by that kind of thing. Those generative models still had to be trained on genuine data of some sort or another. I personally think it's sort of disturbing that someone went and likely hashed the products of, potentially, a bunch people's traumas into a pure mathematical structure that can produce more of it on demand.
At best it has the same marginal effect on children as regular loli, at worst someone's abuse got turned into a component of a disturbing numeric Potpourri. There is also an interesting case for, like, legislation here. Idk about the law side of things, but a generative model trained on actual real CP isn't itself CP, you can't even recover the original images used in training. So I don't even know the legal status of this nightmare.
Imagine explaining to the Unabomber that while he was locked up we figured out how to make computers produce child pornography lmao
