George is another popular robot, courtesy of http://www.jabberwacky.com/george.
Here's my coversation with it. It didn't go that well:
George: "Hello. I'm George."
User: "Hello, George. This is the Freeman. Are you trying to take over the world?"
George: "No. I am not trying to take over the world, why are you asking that?"User: "Scientists are concerned that artificial intelligence may one day do that."
George: "No, in general scientists are quite intelligent."
User: "And you are not. Thank you robot."
(Long pause)
George: "I am not a robot. I am a human being."
User: "Sure you are. And I'm an algorithm."
George: "Your algorithm allows you to flirt with women?"
User: "Badly. But that's not the point."
Here's the video of the conversation, which you can read if you have super vision.
Nightline Online did a piece on George in 2006.
