I don't know whether I am reading too much between the lines, but Mark Zuckerberg is supposed to be a lover of classical literature. Isn't there a tiny connecting dot answering how did he happen to get hit by the idea connecting people and what they would like, inspite of being a near-solitary person.
I don't mean someone being good and writing a book. I mean it in the old sense of the word. Contributing to more than one non-allied fields. Like someone who's a painter and also a sculptor would not be called a polymath.
But someone who is recognised as a polymath. Jared Diamond for instance.
