Acceleration of information

Here are the opening sentences of the Wall Street Journal's review of the book Abundance by Peter Diamandis and Steven Kotler:

If every image made and every word written from the earliest stirring of civilization to the year 2003 were converted to digital information, the total would come to five exabytes. An exabyte is one quintillion bytes, or one billion gigabytes—or just think of it as the number one followed by 18 zeros. That's a lot of digital data, but it's nothing compared with what happened from 2003 through 2010: We created five exabytes of digital information every two days. Get ready for what's coming: By next year, we'll be producing five exabytes every 10 minutes. How much information is that? The total for 2010 of 912 exabytes is the equivalent of 18 times the amount of information contained in all the books ever written. The world is not just changing, and the change is not just accelerating; the rate of the acceleration of change is itself accelerating.


It sounds an awful lot like what Robert Anton Wilson used to write about the acceleration of information, does it not? The rest of Michael Shermer's review is here.
