I think we can compare the human brain and LLMs on a bunch of capabilities today, and see how we compare. By my reckoning:

- LLMs have better long term memory (they know more than any human) and more working memory (LLMs have fast, uniform access to their whole context window).

- LLMs are faster than we are.

- Humans have online learning (we can do simultaneous learning and inference), giving us advantages in many novel tasks.

- We can learn concepts from far less data. And we can manage our mental context more smoothly.

- We seem to have better world models than current models. AI video just doesn't look right, somehow.

I expect that these remaining weaknesses can be overcome without resorting to human brain emulation. I see no reason to think that current LLMs are at the limit of what technology is capable of.
