"Suppose for a moment that the automobile industry had developed
at the same rate as computers and over the same period: how much
cheaper and more efficient would the current models be?  If you have not
already heard the analogy, the answer is shattering.  Today you would be
able to buy a Rolls-Royce for $2.75, it would do three million miles to
the gallon, and it would deliver enough power to drive the Queen
Elizabeth II.  And if you were interested in miniaturization, you could
place half a dozen of them on a pinhead."
