One of my favorite podcasts, Radio Lab, recently posted this episode, Talking to Machines.  You can listen here, or click through to the program page.

"We begin with a love story--from a man who unwittingly fell in love with a chatbot on an online dating site. Then, we encounter a robot therapist whose inventor became so unnerved by its success that he pulled the plug. And we talk to the man who coded Cleverbot, a software program that learns from every new line of conversation it receives...and that's chatting with more than 3 million humans each month. Then, five intrepid kids help us test a hypothesis about a toy designed to push our buttons, and play on our human empathy. And we meet a robot built to be so sentient that its creators hope it will one day have a consciousness, and a life, all its own."
I think this podcast will be of interest to all my geeky student friends at ISOCS (particulary the last segment)!
