Steve Jobs "bicycle for the mind" analogy is more potent than I initially thought.

When got past the bicycle phase where we augment our body with technology but still leave room for our body to improve. We got into the automobile phase where only the goal matter and the body is not participating (and improving) anymore.

(well, except maybe for F1 which are bona fide athlete, but your average driver in a traffic jam is most certainly not a F1 driver)
