“Then I turn on one of my favorite machines. It’s about the size of a book. It has a glowing window inside it. A single page. But I only need one page because its contents change at my command. Sometimes there are words, sometimes photographs, sometimes both. The photographs can move and talk. The stuff in the book can be written by anyone in the world, even as I’m reading it. There’s more in that book than I could ever read. It provides me with unbelievable advantages. Anything I don’t know, I can find out in a few seconds. I can get instructions on how to do pretty much anything that has ever been done. I can summon complete histories of almost any person or culture you could name, expert opinions on anything at all, unlimited advice, unlimited entertainment, unlimited information. I can buy pretty much anything from where I’m sitting, and have it brought to my door. I can even write anything I want and publish it myself. I don’t need permission or credentials. The whole world could read it.”
