Ask Jonathan Koomey About 'Koomey's Law'
A few weeks back, we posted a story here that described Koomey's Law, which (in the spirit of Moore's Law) identifies a long-standing trend in computer technology. While Moore's prediction centers on the transistor density of microprocessors, Jonathan Koomey focuses instead on computing efficiency — in a nutshell, computing power per watt, rather than only per square nanometer. In particular, he asserts that the energy efficiency of computing doubles every 1.5 years. (He points out that calling this a "law" isn't his idea, or his doing — but it's sure a catchy turn of phrase.) Koomey has agreed to respond to your questions about his research and conclusions in the world of computing efficiency. Please observe the Slashdot interview guidelines: ask as many questions as you want, but please keep them to one per comment.
What is your take on the interpretation of Futurists -- like Raymond Kurzweil -- in regards to extrapolating these 'laws' out to extreme distances?

A lot of consumer grade machines have begun focusing on multicore chips with a lower frequency to provide the same or better perceived computing performance than a high frequency single core chip. What happens when a technology like this subverts our craving for higher transistor density? Can you argue that your "law" is immune to researchers focusing on some hot new technology like a thousand core processor or a beefed up system on a chip in order to improve end user experience over pure algorithm crunching speed?
