In 2016, Google DeepMind's AlphaGo defeated Lee Sedol, one of the world's top players of Go, an ancient board game long considered too complex and intuitive for computers to master. For many in finance, the moment raised an unsettling question: if machines could outthink humans at Go, what would they do to the business of picking investments? Jeff Tarrant, founder of Protégé Partners, has spent his career evaluating hedge fund managers and the edge they claim to have, and he famously took the other side of Warren Buffett's ten-year bet that hedge funds could beat the S&P 500. In this episode of War Stories over Board Games, Tarrant considers what AlphaGo's victory might mean for hedge funds, the future of human judgment in investing, and whether the industry is approaching its own singularity.
