Silicon Valley is the centerpiece of a very specific kind of bro culture – a culture that has had a certain winner-take-all mojo over the years, but which may be running its course. To test this thesis, I present you with Elon Musk and Mark Zuckerberg, founders of such landmark companies as Tesla, SpaceX, and Meta (aka Facebook). They are both innovators, admirable risk-takers, and bazillionaires. They’ve also struggled to evolve; to have early, vaunted reputations as wise men correspond with equally wise management and wise decisions as the world around them changed.
