Alex Pang ’s amusing new book The Distraction Addiction addresses those of us who feel panic without a ce ll phone or computer. And that, he claims, is pretty much all of us. When we ’ re not online, where we spend four months annually, we ’ re engaged in the stressful work of trying to get online. The Dis tracti on Addiction is not framed as a self-help book. It’s a thoughtful examination of the ers of our computing overdose and a historical overview of how technological advances change consciousness. A “ professional futurist ” , Pang urges an approach which he calls “ contemplative ( 沉思 的) computing. ” He asks that you pay full attention to “ how your mind and body interact with computers and how your attention and creativity are influenced by technology. ” Pang ’s first job is to free you from the common misconception that doing two things at once allows you to get more done. What is commonly called multitasking is, in fact, switch-tasking, and its harmful effects on productivity are well documented. Pang doesn’t advocate returning to a pre-Inte rn et world. Instead, he asks you to “ take a more ecological ( 生态的) view of your relationships with technologies and look for ways devices or media may be specific tasks easier or faster but at the same time your work and life harder. The Distraction Addiction is particularly fascinating on how technologies have changed certain fields of labor—often for the worse.

As one architect puts it, “Architecture is first and foremost about thinking... and drawing is a more productive way of thinking” than computer-aided design. Somewhat less amusing are Pang’s solutions for kicking the Internet habit. He recommends the usual behavior-modification approaches, familiar to anyone who has completed a quit-smoking program.
