For those of you that saw I-Robot, you will remember that Will Smith had a fake arm. It looked and acted real. Well, soon, this may not be sci-fi, but reality. I am sure that this will bring up questions on just how much human is human.. But, leaving those matters aside, the technological development is wonderful. This will certainly help people. Any body part could be replaced and offer a person a chance to live a normal like. I am sure that with enough medical testing, they will also be able to give it feeling as well. The brain controls it all, they just need to be able to smulate it. I am sure they will even be able to get rid of the pain and just keep the feeling.
