This article talks about the problems with developing robots in to machines that are able to think for themselves, and not just do basic manufacturing functions. They are starting to teach robots to walk more human like and have them perform hand gestures. Do you think that robots will ever really turn in to "humans" and be able to coincide with the rest of the human race??? I don't think so. Call me a pesimist, but I just don't think that they can get a hunk of metal to think for itself, I mean after all, they can't get every human to have the same standard intelligence.
