From the article: "I heard amputees say they sometimes didn't wear a prosthetic hand at all, because what they feared when they did wear one - one that was a very good disguise - was that moment when the people they were speaking to for the first time realized that it was artificial. Some of them said they'd actually like to get that moment over and done with at the very beginning, and would welcome a hand that was obviously not a human hand, but had other good qualities." I wonder if Pullin was referring to the repulsion that humans can feel towards something as it approaches a more humanistic state. This is otherwise known as the Uncanny Valley hypothesis http://en.wikipedia.org/wiki/Uncanny_valley http://en.wikipedia.org/wiki/Uncanny_valley His assertion towards eyeglasses shortly after seems to reinforce this fact. (edit: sorry, not fact - concept) I'd be keen to see how people's reactions to prosthetics would change if the need to have them look human-like was removed. Get some top industrial design talent onto it... perhaps see if someone can convince some design guys from Apple to do some pro-bono designs.
