Radio Lab, one of the best radio shows around, just aired an hour long expose on why self-aware robots must be stopped. It exposes a robot plot to seduce and kill the lonely and introduces us to the evil people behind the Furby and the world's most sentient robot: Bina48.
It's a must listen. Of course, they did miss the most important part of the Bina48 story. That being, oh I don't know, the fact she's conspiring to take over the world.
