You keep referring to this as revenge porn which to me is a case where someone spreads nudes around as a way to punish their current or former partner. You could use AI to generate material to use as revenge porn, but I bet most AI nudes are not that.
Think about a political comic showing a pro-corporate politician performing a sex act with Jeff bezos. Clearly that would be protected speech. If you generate the same image with generative AI though then suddenly it’s illegal even if you clearly label it as being a parody. That’s the concern. Moreover, the slander/libel angle doesn’t make sense if you include a warning that the image is generated, as you are not making a false statement.
To sum up why I think this bill is kinda weird and likely to be ineffective, it’s perfectly legal for me to generate and distribute a fake ai video of my neighbor shooting a puppy as long as I don’t present it as a real video. If I generate the same video but my neighbor’s dick is hanging out, straight to jail. It’s not consistent.
