||| How fast did you say? |||
We all sense that technology is moving fast, but how fast exactly? In
this month's _Scientific American_ W. Brian Arthur takes a good shot at
answering that question, and the answer is: 10 million times faster than
biological evolution. His argument  isn't bulletproof but it is cer-
tainly thought-provoking. My thanks to Scientific American magazine for
their enlightened policy of posting the full content of each issue on
the Web at the same time as it hits the newsstand.
