If I’d lived in the late eighteen hundreds I might have written a story predicting that strange vehicles would soon move across the landscape of the United States and would kill 2,000,000 people in a period of seventy years. Science fiction is not just the art of the possible, but of the obvious. Once the automobile appeared you could have predicted it would destroy as many people as it did. (Emphasis added)
