I’m still impressed by Arthur C. Clark. Not only did he write 2001: A Space Odyssey (the book and the movie), he contributed to the development of geostationary satellites as a communications technology.
This clip is fascinating. He’s right about the communications (though a lot of it is Internet, not satellite), and dead wrong on the cities. Cities are continuing to get bigger, despite advances in communications.
