My immediate thought was Harry Harlow's wire mother/rag mother experiments with Rhesus Monkeys (CW: live animal experimentation - https://en.wikipedia.org/wiki/Harry_Harlow#Monkey_studies) which were an early exerpiment showing that it's really, really bad for primates to be socially isolated. A bunch of polar expeditions were demonstrating the same thing about a decade prior.
Recently we've had a whole bunch of movies about men failing the Turing Test regarding their digital waifus - Blade Runner, Her, Ex Machina, Archer. There are like five different TvTropes pages directly related to this question. And you can go back all the way to Hellenic Greece, with the story of Pygmalia and Galatea, to get the OG "Incel falls in love with body pillow" narrative.
That's what happened with the AI story/adventure services as well, after restrictions got put in on sexual and particularly on stuff involving kids, even just having an underage character in an otherwise sfw story would trigger the AI to halt the story and reset or delete paragraphs.
