An LLM is an algorithm. You can obtain the same result as a SOTA LLM via pen and paper it will take a lot of long laborious effort. That's ONE reason why LLM's do not have cognition.

Also they don't reason, or think or any of the other myriad nonsense attributed to LLM's. I hate the platitudes given to LLM's it's at PHD level. It's now able to answer math olympiad questions. It answers them by statistical pattern recognition!

A brain is an algorithm. Given an unreasonably precise graph of neurons, neurotransmitter levels at each junction, and so on and so forth, one could obtain the same result via pen and paper. It will just take a lot of long laborious effort. That’s ONE reason why brains do not have cognition.
