“One of the things that separates us from primates is that we’re tool builders. I read a study that measured the efficiency of locomotion for various species on the planet. The condor used the least energy to move a kilometer. And, humans came in a third of the way down the list. But, Scientific American tested the efficiency of locomotion for a man on a bicycle. And, a man on the bicycle blew the condor away; it was completely off the top of the charts. And, that’s what a computer is to me. It is the most remarkable tool that we’ve ever come up with and it’s the equivalent of a bicycle for our minds.”—Steve Jobs.
