I love how people talk about not using electricity with various groups and how they did it for hundreds of thousands of years.

Completely missing that their own ancestors did the same thing until at most 150 years ago. In fact, i know my father had no electricity for the first part of his life and he lived in Alberta, not exactly the middle of the congo.

Not using electricity is not the exception, its the rule. Until very recently in human history having grid power was impossible.
