I don't see the problem. I don't necessarily think it is good for society, but IMO producing erotica is nowhere near as much of an "AI safety" concern as fomenting violence, distributing misinformation, or facilitating psychosis, all ways in which LLMs are hurting people right now all the time. It is ludicrous to me that it was ever lumped in with phenomena like that. I hear the "think of the children" arguments ofc but I'm not talking about children, I am talking about adults, who already consume tons of porn, and already consume AI generated porn too, in fact.
It's a "do everything" machine! It will be able to do things you don't like. Don't get it twisted, what the corpo & religious puritanical segments of America don't like != unsafe for human consumption.
