I've been away. Perhaps you mean by "nanocomputer" something more
than a massively parallel machine.
But something tells me that in 100 generations, using 19th century
knowledge, we could breed humans any five-year-old of whom could
dispatch Kasparov. Chess is trivially easy when compared to the
skill it takes to, say, master a language the way a child does.

Maybe so, but that's because you're using chess rather than something
less limited, say NxN go, or something even that does not have simple
rules.
The power of algorithmic superiority---just look at what the general
purpose and very slow human brain can do (Hawkins' book)---surely is
exponentially superior to the mindless crunching of Big Blue.
