According to Mr John Freeman (2009, “Not So Fast,” WSJ, Aug 21, 2009):
As communications speed up, so can “brain overload.” This begs the question of just how fast communications should go. Perhaps the speed of thinking could provide a useful governor.
Speed used to convey urgency; now we somehow think it means efficiency.... There is a paradox here, though. The Internet has provided us with an almost unlimited amount of information, but the speed at which it works—and we work through it—has deprived us of its benefits. We might work at a higher rate, but this is not working. We can store a limited amount of information in our brains and have it at our disposal at any one time. Making decisions in this communication brownout, though without complete information, we go to war hastily, go to meetings unprepared, and build relationships on the slippery gravel of false impressions. Attention is one of the most valuable modern resources. If we waste it on frivolous communication, we will have nothing left when we really need it.
