Cynthia Breazeal's "Your new Best Friend may be a robot" lecture presents interesting ideas about how human/robot interaction is different and more powerful than other human/technology interactions. Thanks to Colleen Wells (Marshall Middle School, Olympia, WA) for this link.
Update: as a teacher-user pointed out in the commetns below (thanks, Laban), this original link was removed by CNN.
Here is a link describing some of Cynthia's work.
