“What are LLMs but humans with extreme amnesia and no central coherence?”

LLMs are nothing alike to compare them with anything close to what’s going on in a brain. It’s all probabilistic and the closest comparison I can think of is comparing a bird with a plane - both fly, but well…

Care to elaborate? Is it well established that brains do not work at any level probabilistically?

I understand the mid-level abstraction is clearly different between LLMs and brains. The whole made of meat vs wires, etc, to start with.

But, honestly asking. I can't see how they can differ in a fundamental level in the specific regard of probability. Either both are probabilistic, be it explicitly in its construction or at a fundamental (quantum?) level, or deterministic again at either level, if we go with the mecanicist vibe.

Am I missing something?

Do we actually understand the inner workings of human brains well enough to state with any confidence how much they are alike (or different) to an LLM? Do we have any understanding how a neural network inside a human brain formulates sentences and chooses words?

I would be interested in an article exploring in detail how the brain's network is different from an LLM, but just saying "it's like comparing a bird and a plane" isn't particularly enlightening.

Yea, I really wish people would stop anthropomorphizing LLM's. It is completely counterproductive to the science, and creates a lot of snake oil salesmen.
