Back in May, we brought you an episode about the life of Japanese billionaire Masayoshi Son, who at that time had just raised his $93 billion tech fund. This week, we'll play you a wide-ranging conversation that Son had for a Bloomberg TV series called The David Rubenstein Show: Peer-to-Peer Conversations. Among the topics Son discusses: the dot-com crash in which he lost much of his wealth, the 45-minute conversation he had with one investor that led to a $45 billion commitment, and his vision for the future of humanity.
