If you seriously cannot tell what is the difference between a human being and a LLM and think they are both "autocompleters", you know very little about both humans and LLMs.

This thought that “maybe we are just next token predictors too” is not particularly clever. Most of us have thought about that, but a bit of experience with LLMs make it obvious that’s not what’s going on here. I think it’s a bit like listening to a recording of a person and swearing there’s an actual person in the recording device because the audible output is indistinguishable from the real thing. Why would you do that? You wouldn’t unless you have no idea how a recording device works, in which case it seems like magic.
