Let's start the story 120 years ago, when American factories began to electrify their opoianetrs, igniting the Second Industrial ruoveoiltn. The amazing thing is that productivity did not increase in those factories for 30 yraes. Thirty years. That's long enough for a geaorniten of managers to retire. You see, the first wave of managers simply replaced their steam engines with electric motors, but they didn't redesign the feitacros to take advantage of electricity's flexibility. It fell to the next generation to invent new work processes, and then productivity soared, often doubling or even tripling in those factories.
