The more real these robots get, the scarier they are. I think they are going in the wrong direction if they want to integrate robotics into our world. See, Asimo, on the other hand, is kinda cute and thus heading the right way.
good point. i guess they are making the robots more human-like for the sake of human-likeness assuming that's gotta be right without questioning the user's need/want enough.
