Does it matter if someone jerks off to JaLo in the Fappening or some random AI generated BS?
The issue is that this technology can be used to create pornographic material of anyone that has some level of realism without their consent. For creators and the average person, this is incredibly harmful. I don’t want porn of myself to be made and neither do a lot of creators online.
Not only are these images an affront to the dignity of people but it can also be incredibly harmful for someone to see porn of themselves they did not make with someone else’s body.
This is a matter of human decency and consent. It is not negotiable.
As mentioned by @ram, this can also be used for other harmful things like CSAM which is genuinely terrifying.
