A variant of the current law also makes an appearance:
"The amount of money flowing through capitalism would astound you. The number and variety of firms participating in the economy would astound you."
My picks are:
"Startups are (by necessity) filled with generalists; big companies are filled with specialists. People underestimate how effective a generalist can be at things which are done by specialists. People underestimate how deep specialties can run. These are simultaneously true."
"You radically underestimate both a) how much you know that other people do not and b) the instrumental benefits to you of publishing it."
