> This is sort of like the QWERTY keyboard layout: originally designed to slow down typists so they wouldn't type faster than the typewriters of the day could handle. That constraint is now long obsolete, yet we're still stuck with it. Except that wasn't really the reason. The reason was to prevent the keys from jamming (by locating common letters and sequences of letters away from each other); the fact that it tended to slow typists down was only a side-effect.
