The actual scary use case for AI porn is that if you can get 50 or more photos of the same person's face (almost anyone with an Instagram account), you can train your own LoRA model to generate believable images of them, which means you can now make "generic looking" porn with pretty much any person you want to see in it. Basically the modern equivalent of gluing cutouts of your crush's face onto the Playboy centerfold, only with automated distribution over the Internet...
AI is still a brand new tech. It's like getting mad at AM radio for being staticy and low quality. It'll improve with time as we get better tech.
Personally I can't wait to see what the future holds for AI porn. I'm imagining being able to get exactly what you want with a single prompt, and it looks just as real as reality. No more opening 50 tabs until you find the perfect video. Sign me the fuck up.
The article mentioned that at least one OnlyFans creator reached out to make a model of their own content and also mentioned that some OnlyFans creators outsource writers to chat with fans. I don't think this will meaningfully affect cam girls' jobs. Once we are able to make live animated images realtime with convincing speech and phrases then probably.
