If anything B offered more detailed information and talked about stuff actually happening to them.
Might make sure you eyes didn't peak down to the answer before you read the whole thing :)
I didn't. I'm in AI. Look at how B mechanically extends the conversation over and over by picking out a word in A's response that it actually knows something about. Then it extends the conversation by talking about that thing. In other words, it controls the conversation by making sure it stays on its turf. Sounds smart but unlike humans, it actually listens to the other guy :)
It's still a very impressive program. I suspect it uses the CYC database, which is free in its public form, to access common sense knowledge.
