I think you lose that draw of interactivity when you’re essentially reading someone else’s RP, though.
There are things like the character(s) you interact with, the initial setting, and some background information predefined, but the responses/evolution of the RP vary depending on things like the model used and the user's interactions.
It's somewhat like taking a D&D setting/scenario. Each group plays it differently.
As much as it's nice to know another shares my interest (and will partake in it with me), I can't always get that.
When I can't get that, LLMs are not a worthless substitute, especially if what I actually want is just to play out a situation.
I want to act and then get back a description of reaction. LLMs can describe reaction, therefore I find value in them.
Like how in D&D you go to do whatever and the dungeon master tells you what happens in response. LLMs fit there for me.
They don't fill the void of social interaction or anything like that, but I don't strictly need that here.
Take a look at services like AI Dungeon to see the kind of thing I'm talking about.
It doesn't really replace social anything, but it's kind of like text adventure. It's plenty interactive enough.
Like, "why not both?"
Also finding AI-generated content to similar tastes is a great way to potentially finding buddies. I've made a lot of friends from certain ventures
