Bruce Sterling gave a speech at the North American Summer School in Logic, Language, and Information (NASSLLI) on the eve of the Alan Turing Centenary, and delivered a provocative, witty and important talk on the Turing Test, gender and machine intelligence, Turing's life and death, and art criticism.
If you study his biography, the emotional vacuum in the guy’s life was quite frightening. His parents are absent on another continent, he’s in boarding schools, in academia, in the intelligence services, in the closet of the mid-20th-century gay life. Although Turing was a bright, physically strong guy capable of tremendous hard work, he never got much credit for his efforts during his lifetime.
How strange was Alan Turing? Was Alan Turing a weird, scary guy? Let’s try a thought experiment, because I’m a science fiction writer and we’re into those counterfactual approaches.
So let’s just suppose that Alan Turing is just the same personally: he’s a mathematician, an early computer scientist, a metaphysician, a war hero — but he’s German. He’s not British. Instead of being the Bletchley Park code breaker, he’s the German code maker. He’s Alan Turingstein, and he realizes the Enigma Machine has a flaw. So, he imagines, designs and builds a digital communication code system for the Nazis. He defeats the British code breakers. In fact, he’s so brilliant that he breaks some of the British codes instead. Therefore, the second World War lasts until the Americans drop their nuclear bomb on Europe.
I think you’ll agree this counter-history is plausible, because so many of Turing’s science problems were German — the famous “ending problem” of computability was German. The Goedel incompleteness theorem was German, or at least Austrian. The world’s first functional Turing-complete computer, the Konrad Zuse Z3, was operational in May 1941 and was supported by the Nazi government.
So then imagine Alan Turingstein, mathematics genius, computer pioneer, and Nazi code expert. After the war, he messes around in the German electronics industry in some inconclusive way, and then he commits suicide in some obscure morals scandal. What would we think of Alan Turingstein today, on his centenary? I doubt we’d be celebrating him, and secretly telling ourselves that we’re just like him.
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.
