But this isn’t a question of ME being dependent on electricity to do my job, or of YOU being dependent on electricity to cook your dinner. The claim is that human civilization depends on electricity.
If that claim is true - and for some pockets of humanity it may very well be, as we discover with every blackout - then “civilization” is hardly a fitting term for such cultures. But civilization existed before electricity. And if plasma balls from the sun wipe out electricity, civilization will exist without it.
Oh, maybe not in New Orleans or Detroit. But those cultures have only the thinnest veneer hiding their barbarianism anyway. Turn out the lights and that veneer is stripped away. Then you’ll see horrors galore.
