The media tends to hyperbolize and boosterize technologists and the work that they do, creating all kinds of absurdly over-the-top titles for them. But when CBS’s 60 Minutes dubbed Kai-Fu Lee “the oracle of A.I.” earlier this year, it was actually a spot-on assessment. Lee has indeed been at the forefront of the field for more than three decades and is without question an artificial intelligence visionary. There are few people in the world who understand A.I. so astutely, especially within so many social and cultural contexts. His accolades speak volumes: In 2013, Lee was named to that year’s Time 100 list of the world’s most influential people, and this January, he was named co-chair of the World Economic Forum’s A.I. Council. His new book, A.I. Superpowers: China, Silicon Valley, and the New World Order, quickly rose to become a New York Times bestseller.

Lee’s got one extraordinary résumé: After receiving a B.S.in computer science from Columbia University in 1983, he went on to get his Ph.D. in 1988 from Carnegie Mellon, where developed Sphinx, the first-ever speaker-independent continuous speech recognition system. In 1990, he joined Apple as a research scientist, heading up multiple R&D groups there for several years. From 1998 to 2005, he worked at Microsoft, where he established what would become Microsoft Research Asia, and later, upon returning to the U.S., he was named a vice president at the company. In 2005, he decamped to Google, resulting in a widely publicized five-month legal battle with Microsoft. Once settled, Lee helped bring Google to China, overseeing its growth and operations there for four years. Lee now runs Sinovation Ventures, a venture capital firm that invests in start-ups in China, many of them in the A.I. space. As of a year ago, according to Bloomberg, Sinovation had $2 billion under asset management with more than 300 companies in its portfolio.

On this episode of Time Sensitive, Lee shares with Andrew Zuckerman his fascinating story of emigrating from China to Oak Ridge, Tennessee, at age 11; why he remains rationally optimistic about A.I. (and its increasingly potent presence in our lives); and how a recent bout with cancer drastically altered his outlook on life and work.
