Re: Credit where credit is due....
In Expanded Universe, Heinlein's predictions in 1951? (I think) about the world in 2001 included battery-powered personal telephones approximately the size of a pack of cigarettes. In "The Moon is a Harsh Mistress" in 1965, you of course have Mike the sentient computer who runs the phone and computer communications on the Moon. Sure looks like the Internet to me -- circa perhaps 1998.
Welcome to the board!
