«The Internet, of course, is seen in a rear-view mirror par excellence. Its critics are prone to see it as a television screen; its devotees, including me, are inclined to see it as an improved kind of book. But the truth of the matter, yet to be fully determined, is that the Internet is and will be a combination and transformation of both books and other media such as telephone as well, and thus is something much more, much different from any prior media. The rear-view mirror cannot tell us what that is, but it can remind us not to get too mesmerized by reflections of the immediate past. The driver who looks only into the rear-view mirror, or even too often, and accords consequently short shrift to the road ahead and its new possibilities can quickly end up on the side of the road, or worse.» Levinson 16
