Update: David (of Simulation Weblog) has weighed in on this with some really good points. Read the comments of this post for more -- & Librarians take note:
"...Sometimes growth comes from efficiency. (Look how EBay recycles junk! or - sorry! - how Google cuts down on the number of trips we have to make to reference libraries). What if we applied modern database/ surveillance/ simulation techniques to road traffic management instead of surveillance, for instance - how much gasoline, time and lives might this save?"
The conversation continues...
Further comments are welcome.
And if you don't know Sven, you ought to.
