This November, 1939 Popular Science article fantasizes about a futuristic "skyscraper airport" for the "city of tomorrow." Pretty good predictions, except they missed the whole no-shoes, no-liquid, no-dignity policy. Link
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
