Neural interfaces and prosthetics will do away with human disabilities.
The best way to predict the future is to invent it and that is exactly what Hugh Herr has done. At the age of 17, Herr was an accomplished mountaineer, but during an ice-climbing expedition he lost his way in a blizzard and was stranded on a mountainside for three days. By the time rescuers found him, both of his legs were frostbitten and had to be amputated below the knee. Once his scars healed, Herr spent months in rehab rooms trying out prosthetic legs, but he found them unacceptable: How could he climb with such clunky things? Surely, he thought, medical technologists could build replacement parts that wouldn’t slow him down.
