Economics
Creative Destruction
You stand at the back of a print shop at noon. The cast-iron cutter shakes the table as it chews through a stack of cards; the handwheel chatters; oil smells like metal and walnuts. On the counter beside it, a sealed carton opens: a smooth, quiet unit about the size of a loaf pan. When it powers up, a thin red band of light runs straight through its center. The cutter's base shows a hairline crack. The new machine hums, takes a sheet, swallows it whole, and the room gets calmer.

Markets change by wrecking their own furniture. The car broke the horse trade and fed the oil fields. The smartphone shattered the point-and-shoot and the pay phone in the same decade. Streaming cracked the DVD case; tractors folded the wheat binder. The line of progress runs straight through both machines — the old splits so the new can use its parts: workers, skills, roads, habits. Protection keeps the shell; demand moves on.

Plan for your product to be replaced. Build the next thing yourself, or leave clean space for those who will.
Steven Sasson, 1975
Steven Sasson, a 24-year-old engineer at Kodak in 1975, wired a CCD sensor, scavenged from a new calculator, to a lens and cassette recorder. The camera weighed eight pounds, made 100-by-100‑pixel grayscale images, and took twenty-three seconds to store each frame to tape. He showed his bosses a photo on a television. They admired the trick and worried about film. Kodak filed patents and kept selling rolls. Two decades later, digital image sensors leapt forward; customers followed the pixels, not the emulsion. In 2012, Kodak filed for bankruptcy protection. Sasson’s prototype is in a museum. The process worked as advertised.
