For those interested, there is an awesome link between people like Bush and pioneers like Engebart (and later XEROX PARC), what made these people really genius was not only their (almost prophetic) vision, but they also had the capability to actually sketch (and sometimes implement) their crazy ideas. His early vision for "memex" acted like a "sorcere's spell" when Engelbart first read it in a magazine during WW2.

> By the time he left Berkeley a few years later with a Ph.D. in engineering, he had decided that his mission in life would be, in effect, to turn the memex into reality.

This excerpt is from the early chapters of "Dealers of Lightning: Xerox PARC and the Dawn of the Computer Age". We're living in a reality these giants dreamed, and we managed to mess most of it.
