Depending on how you count, the human brain is between 100 trillion and 1 quadrillion parameters, which is one guess as to why we're so much more sample efficient at learning than LLMs are.
Unless quantum effects do infact play a role in consciousness. It’s not clear they do by any means, but if it did that could shift the understanding of our own minds and consciousness drastically. Otherwise we are just a dense complex network we can reproduce with enough money.
I mean we literally do this every few seconds already with natural birth processes.
One key difference between humans and (current) LLMs is that we can actually judge the material we learn from at the time we're learning it, contextualize it and discard garbage when we spot it.
LLMs need an awful lot of handholding all the time, meanwhile humans get pretty good at it on their own.
