When something like this becomes commonplace will society just sort of get over it. Fake nudes are fake. They only have power because of perceived taboo over the real thing.
I don't want society to "get over" highly realistic fake nudes of high school girls. We have to draw the line somewhere (although I'm not sure how to solve the problem). There have been many cases reported of such images being passed around schools as a form of harassment and bullying. Such incidents are highly damaging to the victims, sometimes essentially forcing them to transfer schools and in a few cases perhaps even contributing to suicides.
That's a non-answer, totally disconnected from the reality of the problem. Harassment is already illegal. Punishing the harassers doesn't undo the damage. And in most cases the harassers are themselves also minors. They often act without really thinking through the consequences, and because they're minors they can't be given severe punishments.
I dunno about that. If they get realistic enough that you can't differentiate between real and fake people will definitely use them to abuse, bully, etc.
Whatever the computer guesstimates as your nude body will always be an estimate. It cannot know what you actually look like under your clothes.
Being able to differentiate real and fake isn't the point. An occasional nude is special. An occasional fake nude is special. An infinite number of fakes nudes might just stop having any real power to abuse.
Sexuality is mostly in the mind and a real nude image has a element of fantasy that a fake doesn't have. The fact that it's just a made up bunch of pixels that has no real meaning in real life is a factor that we haven't yet fully experienced.
