The post I responded to stated that the commenter was just a next-word-sayer, but that's wrong. The similarities you draw aren't really relevant to my reply.

no disrespect intended, however I think my response is relevant, because the broader topic here is whether LLMs and the human mind share similar functions. They both do in fact have a lot of overlapping features, and a fundamental one is predicting next-thing, be that a word, image, or otherwise.
