I never claimed we already know everything about LLMs. Knowing "everything about" anything these days is impossible given the complexity of our technology. Even antennae, a centuries old technology, is something we're still innovating on and don't completely understand in all domains.
But that's a categorically different statement than "no one understands how an LLM works", because we absolutely do.
You're spending a lot of time describing whether we know or don't know LLMs, but you're not talking at all about what it is that you think we do or do not understand. Instead of describing what you think the state of the knowledge is about LLMs, can you talk about what it is that you think that is unknown or not understood?
