The wall between humans and robots is falling. The more robots act like they feel our presense, the more we feel that they are like us. The first video is of Kismit, an early experimental social robot at M.I.T. who interacts with feeling.
The second video is much more lifelike. Many students say this video is disturbing.
Someday it may become hard to tell the difference between a robot and a person. Will social robots change "human nature"? What are the ethical questions raised? What are the possible applications of such technology? Do we want to limit those applications?
