Complex systems are getting to the point where it almost feels as if "someone" is there behind the interface. This impression comes across most strongly in the field of robotics because these agents are physically embodied, much as humans are. We believe that this phenomenon has four primary components: a system must be able to act in some reasonably complicated domain; communicate with humans using a language-like modality;. reason about its actions at some level so that it has something to discuss, and, learn and adapt to some extent on the basis of human feedback. These aspects are discussed in the article.
