John Hennessy on the Leadership Crisis in Silicon Valley

John Hennessy is the chairman of Alphabet, the parent company of Google, and the former president of Stanford. He's just published a fascinating new book, "Leading Matters," and he agreed to sit for an interview about his experiences. Nicholas Thompson: In the book you talk about a growing leadership crisis, and you mention some industries that have been faltering. Did you leave it out deliberately, or do you think there is a leadership crisis in Silicon Valley? John Hennessy: The valley has its share of leadership crises. And I think there's also a growing challenge that these companies have now gotten to the size where their influence on the public is much larger.
