The World According to Google [Steven Levy] "Eleven years ago computer scientist David Gelernter wrote of the emergence of “mirror worlds,” computer-based reflections of physical reality that can increase our understanding and mastery of the real world. Google is the ultimate mirror world, reflecting the aggregate brilliance of the World Wide Web, on which is stored everything: cookie-bake results, Weblogs, weather reports and the Constitution. And because Google is now the default means of accessing such information, the contents of Google’s world matter very much in the real world."
