http://www.ted.com Oxford philosopher and transhumanist Nick Bostrom examines the future of humankind, and asks whether we can -- or should -- alter our fundamental nature to solve our intrinsic problems. He asks us to reconsider three "inevitable" features of life: death, the risk of extinction, and our inability to live consistently full lives. If we could, would we correct these flaws? Can we humans alter our basic nature in ways that will enhance our experiences in the world? Do we want to? No matter what your answer, Bostrom's engaging talk will force you to consider it carefully.
