Dr. Kai-Fu Lee has been at the center of artificial intelligence for decades. Dr. Lee developed the world's first speaker independent continuous speech recognition system, selected as the most important innovation of the year by BusinessWeek, and that was back in 1988. In the three decades since, Dr. Lee has led teams at Apple, Silicon Graphics, Microsoft and Google. In 2009 Dr. Lee left Google to start Sinovation Ventures, which now manages a $2 billion fund focusing on technology startups in China and the United States. His latest book, "AI Superpowers: China, Silicon Valley, and the New World Order," ranks number six on the New York Times Business Books best sellers list.
