The first approximation of an innovation goes only halfway to realizing
its full impact. Two generations ago many people imagined a
horseless-carriage, or automobile. However, very few imagined the
second-order disruption of this horseless carriage -- parking lots and
traffic jams. And virtually no one foresaw the third-order consequence
of this second-order disruption (car plus parking lot) which was
suburbia.
