I'm not any kind of neurologist, but intuitively, the ways in which people seem to learn things varies so much from person to person, it seems highly likely to me that there is no universal format in which our brains store knowledge of facts and movement patterns. This bodes rather poorly for ever doing something like downloading knowledge to the brain Matrix style. Even assuming you had a way to "write" whatever neuron structure stored knowledge, you'd have to first carry out a super-detailed analysis to determine exactly how to encode that knowledge in each particular brain. And God only knows what'll happen if you get it wrong.

Probably something that the brain does very early in life, like around infancy, is to figure out for itself a way to store knowledge and learn how to store new things that it learns in that way. If each one makes it all up for itself, then it stands to reason that they're all different in unpredictable ways. The observed fact that people vary widely in overall intelligence, what they're good and bad at learning, and how they learn it, seems to follow naturally from that.

This idea reminded me of reading this post series on brain evolution:

https://www.reddit.com/r/askscience/comments/jbt562/what_is_...

According to that, the current best-supported theory is that the human brain evolved the ability to think and reason in in a modern way long before they started actually doing it. The ability to actually think like that is only latent, and needs to be exposed to "recursive language" at the right point in the brain's development to actually have it. So if only under the correct stimulus does the brain develop the ability to think, it stands to reason that they don't all work in exactly the same way at a biological level.
