[quote][url=http://www.theguardian.com/science/2013/dec/11/soldier-controls-bionic-arm-using-power-of-thought]A soldier whose arm was blown off by a rocket-propelled grenade in Afghanistan has become the first person in the UK to master a prosthetic limb controlled by thought. Corporal Andrew Garthwaite, 26, has spent two years learning how to move the arm and grip objects after a six-hour operation to have the limb wired into his body at a medical facility in Vienna.[/url][/quote] It's not exactly super advanced, and the aesthetics leave much to be desired, but it's a thing and has potential to become something great. Now people who have lost limbs are finally able reclaim some of what they lost, and maybe there'll come a day where cybernetic limbs are superior to our own flesh. How do you guys feel about this? Would you ever voluntarily replace your arm if a day came where cybernetic arms were better?
