GPT 4 is at a high enough level of performance that mere simple statistics aren't really helping it do any better, it really is developing structures especially in the middle layers that perform some amount of high level understanding.
I don't think that pure next token prediction will always be the optimal way to train and enhance these behaviors, but it's not fair to say that it's unrelated, if this really was just stochastic parroting then LLMs would have topped out way before the level they're at now.
LLMs don't have that sensation (why would they?), that doesn't mean can only be used for text: https://deepgram.com/learn/applications-of-transformer-model...
That sounds like {you think that {people who think LLMs work like humans} believe that {the human sensation of hunger} is merely {saying the phrase "I am hungry"}}.
