Artificial intelligence is, for all the advances we've made, still remarkably artificial; remarkably limited. Sure, Cleverbot can sometimes hold a conversation. Deep Blue can defeat someone at Chess. Saya can smile and interact with people around it. At the same time, however, there's something missing - something integral which all of these constructs grasp at, but can't quite reach. Something fundamentally human which we've not yet been able to replicate in an artificial context.
