Do we know how the human brain performs addition?

I know how it's taught. Internally it has aspects of long addition, and caching, but I don't do perform that algorithmically.

How then does that map to the physical structure of the brain? Do we know that?

You're correct but this isn't a good counterargument. We don't have the opportunity to change how human brains work, so we have to accept them as they are. That's not true of LLMs and there's no necessity that we deploy them immediately.
