Technology is progressing fast. We’re 114 years old, and there are still aspects of the start of the automotive industry and what it meant for personal mobility. Horses don’t serve the role that they used to, but there’s still a lot of horse races that are a big deal, and people still enjoy riding horses. I hope it doesn’t go that far, but it’s certainly a possibility. I think there will always be an aspect of controlling a piece of machinery, of two or three thousand pounds of machinery being controlled by very minute movements of your hand… Taking yourself to the limit, taking the machine to the limit; there’s something in our brain wired to enjoy that, so hopefully that’s always a part of it.
