Information is Expanding 10X Faster than Any Product on this Planet

In February 2007 Kevin Kelly wrote in Wired Magazine:

"Information is expanding 10 times faster than any product on this planet - manufactured or natural. According to Hal Varian, an economist at UC Berkeley and a consultant to Google, worldwide information is increasing at 66 percent per year - approaching the rate of Moore's Law - while the most prolific manufactured stuff - paper, let’s say, or steel - averages only as much as 7 percent annually."
