It's still not at all obvious to me that LLMs work in the same way as the human brain, beyond a surface level. Obviously the "neurons" in neural nets resemble our brains in a sense, but is the resemblance metaphorical or literal?
Digital neural networks and "neurons" were already vastly simpler than biological neural networks and neurons... and getting to transformers involved optimisations that took us even further away from biomimicry.
