Lionel Goettreider read Cat’s Cradle and had a crucial realization, what he called the “Accident”—when you invent a new technology, you also invent the accident of that technology. When you invent the car, you also invent the car accident. When you invent the plane, you also invent the plane crash. When you invent nuclear fission, you also invent the nuclear meltdown. When you invent ice-nine, you also invent unintentionally freezing the planet solid. When Lionel Goettreider invented the Goettreider Engine, he knew he couldn’t turn it on until he figured out its accident—and how to prevent it.
