As something of a futurist, I often consider the concept of contemporary technology seeming barbaric only a few decades/years later. Leeches, bloodletting, wound cauterization, invasive neuro-cybernetic prosthetics requiring surgery (yes, VNS, your end is also near). A time-tested and verifiably inadequate piece of mobility enhancement technology is the wheelchair. It may have assisted millions over the years, but it needs to go. And so it shall!
