In barely one generation we’ve moved from exulting in the time-saving devices that have so expanded our lives to trying to get away from them — often in order to make more time. The more ways we have to connect, the more many of us seem desperate to unplug. Like teenagers, we appear to have gone from knowing nothing about the world to knowing too much all but overnight. […] Writer friends of mine pay good money to get the Freedom software that enables them to disable (for up to eight hours) the very Internet connections that seemed so emancipating not long ago. Even Intel (of all companies) experimented in 2007 with conferring four uninterrupted hours of quiet time every Tuesday morning on 300 engineers and managers. (The average office worker today, researchers have found, enjoys no more than three minutes at a time at his or her desk without interruption.) During this period the workers were not allowed to use the phone or send e-mail, but simply had the chance to clear their heads and to hear themselves think. A majority of Intel’s trial group recommended that the policy be extended to others.
