Have you guys looked at how advanced robotic limbs have become? It seems that robotic limbs are almost as useful as real limbs. Some almost being as if they never lost an arm. I saw a video of a young woman who didn't have any arms, but she got robotic limbs that work almost as good as human hands. Now they are even making legs that can work the same way. Soon enough people will be utilizing walking robot endoskeletons and all that fun stuff.
