"The Xerox Corporation's Palo Alto Research Center, known as Xerox PARC, had been established in 1970 to create a spawning ground for digital ideas. It was safely located, for better and for worse, three thousand miles from the commercial pressures of Xerox corporate headquarters in Connecticut. Among its visionaries was the scientist Alan Kay, who had two great maxims that Jobs embraced: "The best way to predict the future is to invent it" and "People who are serious about software should make their own hardware." Kay pushed the vision of a small personal computer, dubbed the "Dynabook," that would be easy enough for children to use. So Xerox PARC's engineers began to develop user-friendly graphics that could replace all of the command lines and DOS prompts that made computer screens intimidating. The metaphor they came up with was that of a desktop. The screen could have many documents and folders on it, and you could use a mouse to point and click on the one you wanted to use."
