I bet Tom Edison ate a lot of crow. His DC power distribution is gone except for a few isolated cases.
Oddly enough, with modern semiconductors and DC/DC converters, DC power distribution is again becoming popular. EHV for long distances, moderate voltages (40-50V) inside racks and automobiles, a few hundred for solar panels and grid-tie inverters, and the International Space Station, which uses 120V DC power everywhere.
