Should we currently be interested in quadrillions, upper trillions, or, perhaps, larger? Once we become interested in an appropriately large number, what preparations should we be taking so that we can operate at that level? Do we just start putting product out there and collect the value on the open markets, or, do we need to segment markets to maximize value? Can you tell us about any other mistakes you feel Xerox might have made in realizing the value of PARC?
