I don’t believe the AI is generalized by any means. But I think it’s more than a Eliza-style parlour trick.
It does really well with facts but misses subjectivity and nuance. Like I ask it to write stories for Seinfeld or Raymond and it misses the tone and style entirely. But it gets all the names and other factual details right. I find it works incredibly well when you want things that are objective, like code or rhymes or comparisons of things.
