"The poster boy for our superabled future is Oscar Pistorius, an increasingly famous South African sprinter who happens to have had both of his legs amputated below the knee. Using upside down question mark-shaped carbon fiber sprinting prosthetics, called Cheetah blades, Mr. Pistorius can challenge the fastest sprinters in the world."

"The goal for many amputees is no longer to reach a 'natural' level of ability but to exceed it, using whatever cutting-edge technology is available. As this new generation sees it, our tools are evolving faster than the human body, so why obey the limits of mere nature?"

"The fear of the never-ending onslaught of gizmos and gadgets is nothing new. The radio, the telephone, Facebook - each of these inventions changed the world. Each of them scared the heck out of an older generation. And each of them was invented by people who were in their 20s."

"Change creates fear, and technology creates change. Sadly, most people don't behave very well when they are afraid."

"It is a subtle truth that reason is the torch that illuminates the dark corridors of superstition."

"The darkest nights often reveal that the mind is a garden where thoughts are the seeds."

"My movies are unadorned, they're not particularly fancy, I think they're kind of workmanlike in some ways, focusing on the writing and the acting."

"A quiet mind is capable of understanding that every failure is just a stepping stone to greatness."
