The issue I'm curious about on a moral/ethical level is the nudity/sex aspect.
For a lot (I mean a disturbing number) of actresses, particularly young ones, there's this sort of expectation that they do a nude scene or a sex scene when they come of age. It's seen as like a rite of passage. And no one should be expected to show their naked body to anyone for validation, let alone to the entire world, and yet people who have daughters or nieces or sisters they'd be uncomfortable seeing naked or uncomfortable with many other people seeing them naked, will jump at the opportunity to see the just-turned-18 starlet pose nude in a magazine or have a sex scene with her top off in a film.
It's kind of sick, and it's absolutely depraved.
But what if it's an AI? Does it matter? Does the AI being willing to strip naked and show everything mean more real women are expected to? Or can we just have AI actresses do that? There are arguments both ways. I'm personally for, if we're going to use AI at all, using AI performers to replace human performers in sex work on film, in pornography. Take people out of the equation and the danger (of STIs first and foremost, but also the abusive environment) and let AI do that. But then you have people who want to do that, and make a living doing that, and can't or don't want to do anything else. What of them? I really don't know. But as a straight guy who's seen a lot of women naked, IRL and in print/film, I don't really care if it's AI or not, if it's CGI or not, if it's anime or not. But I'd much rather it not be someone's daughter or niece or sister. I'd also much rather it not be someone who has feelings and thoughts and is more than just genitals and breasts and a butt. I think that's a fine use of AI, because the AI isn't more than those things.
I do not want to see AI performers replace human performers in dramatic roles (or comedy but that's not really my genre). If you got a group of "young people" and there's one who gets her tits out on camera and that sells tickets, I'm fine with that character being an AI, even if they get lines. I'd rather that not be a real person. And I think it's just as well for the, er, titillating factor.
