So I guess it hinges in part on what you consider Thomas Edison's day. Also
consider that this is part of a speech and referencing Samuel Insull's day
or Nikola Tesla's day wouldn't work too well.


I'd define "Edison's day" as anything that happensed while he was
alive. Edison died in 1931.

So - was the modern day power grid developed before 1931?
