Nassim Taleb is only interested in one topic: chance. Particularly extreme and rare events, the "Black Swans", the point where improbable chance falls at the intersection of philosophy/epistemology, philosophy/ethics, mathematics, social science/finance, and cognitive science.
Accept no pundit market-trend forecasts of gloom until you hear out Nassim Taleb and his argument of how our daily lives are dominated by ripples from game-changing disruptions no one expected, those glitchevents that Buckminster Fuller called "Unforeseen Leaps in capabilities", what Sun Ra called "the Greater Unknown".
