Engineers at Cornell University wanted to see what would happen when they made two rather clever "chatbots" talk to themselves. The resulting exchange got rather testy and involved talk of unicorns, God, philosophy, and miscommunication--and was not all that indistinguishable from human chatter. However, it was a fair way off from fully coherent human conversation. If this is the extent of robot thought at the moment, I think we still have quite a ways to go before we need to gaze at our robotic counterparts with Hollywood-instilled fear. Though, the "female" robot does ask rather inexplicably if her "male" counterpart would like a body, and he answers in the affirmative just before the discussion ends. Hm. Maybe they are up to something!
