History has a habit of repeating itself. This often happens when the price of a core resource collapses. Consider the story of steel. Before 1856, steel was incredibly expensive and used sparingly, reserved for luxury items like swords and cutlery. Then Henry Bessemer invented a process to blow air through molten iron, and the cost of producing steel collapsed by over 80%. The result was profound. We did not just make cheaper cutlery. We built skyscrapers and suspension bridges. Structures that were physically impossible suddenly became possible and viable.
