David Deutsch on the infinite reach of knowledge
It can be easy to believe that humans are insignificant. We're specks of dust on a random planet in a vast universe. Less powerful than elephants. Fewer than ants. But David Deutsch believes that's all beside the point, because humans possess one unique skill: attaining knowledge. David Deutsch -- Oxford professor, father of quantum computing, recluse -- convinced Chris Anderson years ago to take over leadership of TED with his ideas about knowledge. In this mind-bending conversation, the two dive into his theory that the potential reach of knowledge is infinite. They explore how knowledge first developed, why it sets us apart and what all of these heady concepts really mean for our present and future.
