Host Harry Kreisler welcomes artist and engineer Ken Goldberg from Berkeley. Goldberg discusses robotics in surgery and cancer therapy, and their application in disasters and on the battlefield. Describing several of his recent art projects, Goldberg then discusses complementarities with his engineering research and reflects on the philosophical implications of 'telepresence.' The conversation then moves to military drones, wiki-leaks, and the problem of bringing ethics to a world in which technology changes the nature of war, undermines secrecy, and challenges the legitimacy of the state.
