Humans run on hardware that is both faulty and limited in terms of speed and memory. They have a better "algorithm" how to use the hardware to compensate for it. LLMs run on almost perfect hardware, able to store and retrieve enormous amounts of information insanely quickly and perform mechanical operations on it insanely quickly.

Yet they "make mistakes". Those are not the same as human mistakes. LLMs follow an algorithm that is far simpler and inferior, they simply use the hardware to perform incorrect ("illogical", "meaningless") operations, thus giving incorrect results.

See my other replies for more depth.
