George Dyson is a scientific historian, and the author of several books including Project Orion: The Atomic Spaceship 1957-1965 and Darwin Among the Machines: The Evolution of Global Intelligence, in which he expanded upon the premise of Samuel Butler's 1863 article of the same name and suggested coherently that the Internet is a living, sentient being. His latest book, Turing's Cathedral, has been described as "a creation myth of the digital universe."
