If people are going to a porn site to spend relatively small amounts of money to get "genuine human to human interaction," there are more than a few flaws in their strategy. Unless they're spending many thousands of dollars a month, there could be no reasonable expectation they're getting anything but extremely superficial interactions. If they get mad because they think they should get an e-girlfriend for $10 a month or whatever, I'd say that's on them because of unreasonable expectations.
Honestly, I think gen AI is pretty much inevitable for these kinds of parasocial services, but it will be clandestinely used because otherwise it makes perfect sense for the "content creator." Whatever relationship they think they have is an illusion in their head anyway, and they're probably expending a fair amount of energy to maintain it.
