Jules Verne “20,000 Leagues under the Sea”
Chester Gould, “Dick Tracy” and his wrist watch
Al Capp, ‘Lil Abner’ The Schmoos were supposed to be the Politicians who could turn OUR money into Their money.
George Orwell ‘1984’ a look at the future.....hmmm
Ayn Rand, most of her writings
and more, just some off the top of my head....
Who knows what Star Trek etal will bring us???
Funny aside: according to a later Hanna Barbera cartoon (Harvey Birdman) the Jetsons was set in 2002 at the series start. Grandpa was a young man in the 1960s.
