It sounds like you need to be less condescending and engage with my actual comment.
First, the "hype" is not externally imposed. It's the genuine reaction of hundreds of millions of people to a technology that would have been considered science fiction just four years ago. The fact that I can't be certain you whether you are an LLM or a human is incredible.
Second, the output of the LLM depends on both its weights and the context. If it has seen something in its context window, it now knows it for all intents and purposes. It learns, in other words.
