Neil Degrasse Tyson Talks With Elon Musk About The Future Of Humanity

Neil deGrasse Tyson — public face of science in the United States, spiritual successor to Carl Sagan, etc. — devoted the most recent episode of his radio show to a rather pressing topic: the future of humanity. 

The episode features clips from deGrasse Tyson's recent interview of Elon Musk (of Tesla Motors and SpaceX, among others) along with commentary from co-host Chuck Nice and Bill Nye (yes, the Science Guy).
