Will artificial intelligence help us solve every problem?

Tonight, we hear from Sebastian Thrun. He founded Google X, the semi-secret research facility that began development of Google's self-driving car. SEBASTIAN THRUN, Founder, Google X: Artificial intelligence is to the human brain what the steam engine has been to the human muscle. Before the agricultural revolution, most of us were farmers, and our distinguishing capabilities were our physical strength and agility. And then we invented machines that make us stronger and, all of a sudden, one farmer can make food for 150 people.
