What did Edison think about the way we should get our electricity?

What's rude about pointing out that Edison favored DC over AC??

It's a good thing we went with AC. Do you like watching TV? Do you know why TV's refresh their screens at a rate of 60 times per second? ( The old 480i "interlaced" NTSC TV format refreshed half the TV lines - odd lines on one sweep, even lines the next sweep - at 60 times per second so the net refresh rate was 30 frames per second ).

The reason TVs refreshed their screens at 60 times per second is that they used the 60 Hz or 60 cycles per second AC power as a timing reference. We wouldn't be able to do that with DC power, because there's no timing reference.

Electric clocks also work off the 60 Hz power as a timing reference.

Edison didn't anticipate the need for electric power to also serve as a timing reference. So why be bound to what Edison wanted?
