At the same time I can say with 100% certainty that LLMs (or any current "AI") is in any way, shape, or form, conscious. Not even close. A decade or two ago it was the Internet that was a possible emerging consciousness.
The onus to prove LLMs are conscious is on you making the claim. And if you say we don’t even know what consciousness is, how can you then attribute to an entity?
Definitionally and philosophically, humans are conscious (Descartes et al.) so need no proof themselves
And it's unclear what your actual argument about the nature of consciousness is, aside from what seems like a bald assertion that humans are the only conscious beings.
