I’m not sure. Let us assume that you generate it on your own PC at home (not using a public service) and don’t brag about it and never give it to anybody - what harm is done?
Even if the AI didn’t train itself on actual CSAM that is something that feels inherently wrong. Your mind is not right to think that’s acceptable IMO.
Laws shouldn’t be about feelings though and we shouldn’t prosecute people for victimless thought crimes. How often did you think something violent when someone really pissed you off? Should you have been persecuted for that thought too?
This goes away further than a thought
Who are the victims of someone generating such images privately then? It’s on the same level as all the various fan fiction shit that was created manually over all the past decades.
And do we apply this to other depictions of criminalized things too? Would we ban the depiction of violence & sexual violence on TV, in books, and in video games too?
Society is not ok with the idea of someone cranking to CSAM, then just walking around town. It gives people wolf-in-sheep-clothing vibes.
So the notion of there being “ok” CSAM-style ai content is a non starter for a huge fraction of people because it still suggests appeasing a predator.
I’m definitely one of those people that simply can’t accept any version of it.
