There are “cognitive skills” that contribute to “intelligence”. So then the question is: are those skills a certain kind of knowledge that can be learned?

AFAICT some can be, and many probably cannot be *yet,* and others possibly can't be unless you alter the brain. But it's early days and hard to know. Can aphantasiacs learn to create mental imagery? Not yet, maybe in the future (many have visual dreams!) https://en.wikipedia.org/wiki/Aphantasia 

Some things some people can do, in principle others cannot...on that view. So the human mind is *not* universal, then.

I'm saying: - there can be damage or limitations on the hardware layer - human beings living today have access to a very small set of all possible inputs *and* all possible forms of input; this obscures what is possible in principle, but still means hard practical limitations

Say you got passionate about doing that & it took you 50 years. You'd get faster as you went along, right? How long would the fastest-brained human take? 25 years? Take two humans who want to do it. What's the main factor affecting who'll finish first: brain speed or passion?

I don't know how to estimate that. Maybe 25 years? Maybe 100 years? Does it matter where the human lifespan falls at the point the attempt is made? It's a distraction.
