I found this TED Talk particularly compelling. Part of it is probably just withdrawal from the end of Battlestar Galactica. Since the presenter talks about modern-day battlefield robots, it's easy to imagine these machines becoming more and more like the Cylon "toasters" in the future. Beyond the sci-fi becoming reality angle, the talk goes into some very interesting issues of how people react to the use of war robots. When the warriors are expendable, they are more likely to be used to wage war. Perhaps the most disturbing part of the talk, is the quote from an official who fells that there is no moral quandary with the use of robots on the battlefield, "unless they kill the wrong people. Then, it's a product recall issue."
