 To be clear, they built this great, big, expensive, complicated power station, the first central power station in the world, right? Basically inventing electric light. And when they turn it on, Edison is not there. Right. He was where he needed to be with the people who had funded the whole thing, right? So at 3 p.m. on September 4th, Edison flicked on the switch here at J.P. Morgan's office. And what happened? It went on, as did lights all over the district.
