In the case of the digital revolution is the fire only virtual fire? I own books where you can actually feel the imprint of the type on the page. Ninety percent of readers under 30 will not know what that means or care. So, in a way, the Fahrenheit 451 scenario I described in the illustration has come true. Even the size of the machine is quaint and antique. While this revolution was taking place I was describing it almost weekly in magazines like Time and USNews and Technology Review, trying to keep up with the hardware, inventing new iconography and metaphors and shorthand for what was happening.
