It also talks a lot about very early Internet history, and gives the history of many things which I have not seen others reference, like Lee Felsenstein and Community Memory.
I suspect the book might not be well-known because its author, Jacques Vallée, it mostly known for being a ufologist. I did not know this until after I read the book, though, and the book itself does not contain any references to UFOs. I can wholeheartedly recommend the book, and it’s free to read online!¹
Later books in the same vein like Hackers and Dealers of Lightning are more well-known and seem to be appreciated by many, but this book seems to have been overlooked by most people.
