We admire digital systems for several of their rare computational attributes, such as repeatability (for a given chip), consistency (over each chip) and accuracy. Chips are perfect! These attributes are seldom found in our non-digital worldly experiences. The early mariners often desired to keep track of time to a greater degree of accuracy than could be obtained by just looking at the stars. Knowing that some clocks run fast, and others slow, they often brought several clocks on board, and determined the "actual" time by taking the average of the observed times. This was "good enough". Consider the following facts:

Get real folks — most of the world deals not need this "repeatability, consistency or accuracy", but rather "just good enough". The world accepts "analog computation", where everyone?s watch in the room indicates a slightly different time. Digital systems engineers should join the mariners and see how they can take advantage of this so far untapped luxury and freedom.
