About a year ago, I wrote that I had received a book for Christmas called The Big Switch by Nicholas Carr. I’m a little embarrassed to say that it was only two weeks ago, on my post-holiday flight back to California, that I finally finished it after ten months of letting it collect dust.
Carr’s attitude about the rise of cloud computing, social networking, and all the other web 2.0 buzztrends caught me off guard. While he seems to marvel at and mostly celebrate the speed and scale at which this phenomenon has grown and subsequently become integral to modern life, he does so with a very cautionary and sometimes pessimistic tone. I guess I should have expected as much after reading his piece in the Atlantic last summer (hat tip to Joel for passing it along) called “Is Google Making Us Stupid?”. Though I don’t share all of his concerns, it is refreshing to find a voice like his among the generally over-enthusiastic technorati (myself included).
Carr highlights a particularly interesting threat in the chapter he titles “The Great Unbundling.” While granting that the jubilation over the democratizing and barrier-lowering nature of the Internet is mostly well deserved, he also warns that these characteristics come with potential harm. What harm? In short, Carr argues that the speed and personalization offered by the Internet facilitate our natural human tendency to cluster into isolated groups that can deafen and blind us to differing opinions.
Carr’s main evidence is an experiment conducted in 1971 by a Nobel Prize winning economist named Thomas Schelling. The experiment consisted of a grid of squares and a set of white and black markers. After randomly distributing these markers to represent an “integrated” community, he moved the markers around based on the rule that no one marker could have more than 50% of its immediate neighbors be of the opposite color. This rule, Schelling posited, mirrored a natural instinct that humans possess: to be closer to people similar to ourselves than we are to those who are different. After moving pieces one at a time based on this rule, he ended up with one all-white cluster and one all-black cluster. Self-segregation, Schelling concluded, is the natural result of our instinctual preference to be closer to those that resemble us than to those who differ from us.
Extrapolating from these results, Carr hypothesizes that because the Internet removes so much friction from the market for information, self-segregation will happen much more quickly and completely online than, say, in a once-integrated neighborhood that slowly segregates over many years into two or more distinct socioeconomic or racial groups. In my opinion, however, his interpretation of Schelling’s experiment, and his application of it to the Web, is flawed from the start.

Last Tuesday, my otherwise trusty MacBook sputtered out for the second time in six months. In February, I returned home to find my white plastic-encased sidekick unable to boot up. One new hard drive later, I was back in action (Apple’s awesome Time Machine utility saved me from any data loss). Unfortunately, I had to relive this scenario last week when my MacBook wouldn’t revive after a routine reboot. And so it was, after a painless call to AppleCare tech support, that I shipped my MacBook off to let the wizards work their magic on my poor, sick machine.
