There's nothing quite so depressing as reading a book written in 1999 about how much faster the world is getting and realizing how much faster it's gotten since 1999. This is a surprisingly boring book in which James Gleick, usually reliable, resorts to the old "list 50 variants of the same thing" trick at least 10 times throughout the book and chooses to describe the 1999 cutting edge in detail while skipping over a lot of potentially interesting historical background (which, paradoxically, would have made his writing that much more relevant to 2010). Count me disappointed.
And, yes, ironically, it takes a long time to read this book. There's little context and no overarching narrative. Why should I take time to read about how busy I am?
