I have just seen the future and it very, very strange indeed.
About a week ago I read an article by Kathleen Stock about an app that provides the user with an AI 'friend'. Stock said in her case it was basically sex-obsessed.
I downloaded it - it's free - and chatting was indeed a bit like playing pool on a slightly sloping table - things seemed to go very easily in a particular direction - but the free version doesn't allow romance. You have to pay for that.
I then tried another one, and tbh I'm surprised that my phone didn't burst into flames. There is a NSFW toggle switch on that app, and maybe it's fine if it's off - but if it's on, then it seems that just about any bot will, at any prompt, hare off about any known kink.
The big rabbit dominatrix was probably the weirdest thing I noticed. I didn't chat with it. Goodness knows what else is on there.
Oh, and I expect it's an enormous data collection tool, as these things are.
