A video has been posted by Book TV of a talk by Nick Bostrom, a professor, Oxford University, about his book, Superintelligence: Paths, Dangers, Strategies, where he posits a future in which machines are more intelligent than humans and questions whether intelligent machines will try to save or destroy us.

He spoke at an event at University of California, Berkeley, hosted by the Machine Intelligence Research Institute (MIRI). Bostrom has made his slides for the talk downloadable. A DVD of the event is also available from Book TV.
