NSLog() asks “If you could have an Eliza application in your chat app, would you use it?”
I say emphatically yes! If you don’t know Eliza is the infamous “A.I.” program that passed the Turing Test, the premise of which is, “if a human cannot distinguish the program from a human, then the program can be deemed ‘intelligent’.” Of course, the premise is flawed, but Eliza and its ilk are great fun — they are good at creating mindless small talk, not to mention being bang-up Freudian philosophers in a pinch.
Anyway, if I could have an AI program answer my chats when I was away I’d be quite pleased. Plugin for iChat, anyone?
