Nassim Taleb has never been shy about expressing his viewpoints on a wide range of topics. But lately he's been getting into verbal tussles with people who have long looked up to his wisdom. Whether it's Bitcoiners, venture capitalists, deadlifters, or anti-vaxxers, many people within these communities have admired his philosophy of antifragility. So why has he taken to arguing with them on Twitter? What exactly are they getting wrong about his ideas? And for that matter, why has he himself gotten into cycling lately? In this wide ranging conversation, the author of books such as Antifragile, The Black Swan, and Fooled by Randomness talks about all these topics and more — including how to think about reducing tail risk in one's own life.
