Services like that are about the "personal" (parasocial) connection.

I think we are pretty close to advances in language models, text to speech, and image generation automating the parasocial relationship. When your AI gf looks how you want, (virtually) does whatever you want, and talks to you however and whenever you want - I don't see how OnlyFans and the like will compete.

Comparative advantage and the power of boredom help here. “Hiring” people means you get things you don’t want or didn’t ask for, and that’s a good thing.

Yeah; My gf was a "specialist" in her time at a dungeon while she was paying her way through art college. There will always be 1% of people who can pay for a professional, and 1% of girls who are great at controlling their urination at those guys faces. But realistically, the other 99% of dudes will definitely settle for an intelligent blow-up doll and an AI girlfriend. This is just hijacking the hard wired behavior of testicles. The people who really get cut out of this process are the 99% of girls who are not AI bots or domiatrixes and just want to meet a dude who isn't jacked into porn 24/7.
