Some further developments in neural prosthetics. The present bionic limb is not as agile as a human limb, but it works and will soon be stronger in its ability to heft and grip than the arms and hands that we are born with. It will swiftly become as facile, or more in its movements, as well. How about an extra knuckle and an extra finger equipped with a Swiss Army Knife?
So, the question is, will we come to the point that ladies not only get boob jobs, and guys get their jowls tucked, but humans start to replace their limbs with tech superior to what nature has given us? Would you like to run faster than a Cheetah, or dance with more poise than the most gifted, but unmodified ballerina?
