The World of Robots -- in Love and War

The first conversation between a human being and a robot might well have happened in 1968, in Stanley Kubrick's iconic film 2001: a Space Odyssey. Now, robots are a part of daily life, from factories to more and more homes. The new film Her depicts a romance with an operating system. But robotics often starts with the military. This weekend, the Defense Advance Research Projects Agency, DARPA, is running a contest for robotic emergency responders. Google, Apple, Amazon and many other companies already are deeply invested already in robotic technology. Robots are also finding their way into work places, homes and popular culture. So, it's not hard to imagine they'll penetrate our emotional lives as well. The interaction of humans and robots has become a serious study. When do they help? When do they get in the way? Who's responsible for their actions? Do we need a new code of ethics for dealing with robots?
