Humans can achieve more within one (or two, or a few) narrowly scoped field(s), after a lot of hard work and effort. LLMs can display a basic level of competency (with some mistakes) in almost any topic known to mankind. No one reasonably expects a LLM to be able to do the former, and humans certainly cannot do the latter.

You're comparing apples and oranges.

Also, your comparison is unfair. You've chosen an exceptional high achiever as your example of a human to compare against LLMs. If you instead compare the average human, LLMs don't look so bad even when the human has the advantage of specialisation (e.g. medical diagnostics). A LLM can do reasonably well against an average (not exceptional) person with just a basic grade school education if asked to produce an essay on some topic.
