Will our brains ever be uploaded into a computer? Will we live forever? Richard Jones, physicist at the University of Sheffield and author of Against Transhumanism, talks with EconTalk host Russ Roberts about transhumanism--the effort to radically transform human existence via technology. Jones argues that the grandest visions of the potential of technology--uploading of brains and the ability to rearrange matter via nanotechnology are much more limited and unlikely than proponents of these technologies suggest. The conversation closes with the role of government in innovation and developing technology.
