HEFFNER: I'm Alexander Heffner, your host on The Open Mind. TED Talk curator Chris Anderson joined us recently to consider the danger of artificial intelligence, namely its potential to drive away or make obsolete the moral compass of human beings and civilization as we know it. Of course sometimes, we're our own worst enemy, and we would rather not embrace the present reality. So I've invited today the leading ethicist in the arena of innovation. He's going to help us understand the term techno sapiens as he calls it, with our drones, our supercomputers, our designer babies, and now our 3D printers too. Wendell Wallach is the author of A Dangerous Master: How to Keep Technology From Slipping Beyond Our Control.
