Another fascinating package of hits and misses was H. G. Wells' 1938 book--actually a collection of articles--"World Brain." In some ways it anticipates the Internet in general and Wikipedia in particular. It describes a network of scholars, producing a gigantic encyclopedia, using desktop terminals capable of calling up vast quantities of information. Well, that's the "prophetic" spin. Where he got it ludicrously wrong was that the technology involved microfilm, reels of microfilm be mailed around the world, and, of course, it was a dignified, high-minded community of certified academic scholars. No articles on Pokemon characters, Miley Cyrus, or striptease!
I've occasionally wondered whether Isaac Asimov's "Encyclopedia Foundation" was directly inspired by Diderot or whether he was also thinking of "World Brain."
