From Kevin Kelly's blog: The Technium
"A while back George Dyson sent along this note about the fecundity of manufactured items:
I had to park my car at [Seattle's] SeaTac on Saturday-Sunday and this sparked a small epiphany. It now costs more to park a car at one airport than to rent one at the other end. To my twisted mind, this indicates that machines (taking the automobile as a benchmark) are now self-reproducing so fast we have reached a transition point where machines are cheaper than the empty space they fill."
