For me, that’s kind of the point. It’s similar to how the characters in a novel don’t really exist, and yet you can’t really discuss what happens in a novel without pretending that they do. It doesn’t really make sense to treat the author’s motivations and each character’s motivations as the same.
Similarly, we’re all talking to ghosts now, which aren’t real, and yet there is something there that we can talk about. There are obvious behavioral differences depending on what persona the LLM is generating text for.
I also like the hint of danger in “talking to ghosts.” It’s difficult to see how a rational adult could be in any danger from just talking, but I believe the news reports that some people who get too deep into it get “possessed.”
