“…maybe you’re hallucinating…” and “…I must be hallucinating…” Have been part of human to human communication since the 60s, when people in fact could very seriously have been. It continued on for acid flashbacks and other surreal moments

Thats certainly true, and at least in philosophy similar discourses go back much farther than that!

But the senses are importantly different right? In the former, we are talking about clearly psychological assertions, in the form of skepticism, within an otherwise shared world.

Here it is clearly rhetorical though, right? Talking to GP as if they were LLM. Using it for a not-so-shorthand for "I believe you to be wrong about this".

Its really not a big deal. It's just interesting, I guess, how much the tools tend to master us and change us while we lie to ourselves that its the other way around.

Also, hadn't heard "acid flashbacks" in a long time.. Still waiting for mine!

I've used LSD a few times, but to my knowledge never had any "acid flashbacks". Maybe that's for the best... but seems like it might be fun if one was in a safe environment.

"Maybe you're hallucinating", let alone "let's say you're hallucinating", is a really weird take on someone thinking of a reasonable semantic distinction even if you disagree about its existence or relevance.

Perhaps you can say that to a friend as banter or in a tongue-in-cheek way, similarly to how you might say "I must be hallucinating" about yourself. But as an argument in a discussion with a stranger, it seems rather dismissive and inappropriate.

And it does reek a bit like something stolen from LLM terminology.
