The most comprehensive case that has ever been made for why nearly everyone should become a polymath in a modern knowledge economy. 

If being a generalist was the path to mediocrity, why did the most comprehensive study of the most significant scientists in all of history uncover that 15 of the 20 were polymaths? Newton. Galileo. Aristotle. Kepler. Descartes. Huygens. Laplace. Faraday. Pasteur. Ptolemy. Hooke. Leibniz. Euler. Darwin. Maxwell — all polymaths.

If being a generalist was so ineffective, why are the founders of the five largest companies in the world — Bill Gates, Steve Jobs, Warren Buffett, Larry Page, and Jeff Bezos — all polymaths (who also follow the 5-hour rule)? Are these legends just genius anomalies? Or are they people we could and should imitate in order to be successful in a modern knowledge economy?
