Do you know what power stations feed your electrical circuit? Do you know which transformers are most critical to keep you in service? Do you know who manufactured them?
Do you know where your water comes from? Which facilities treat it? How it's treated?
Can you name your senators, house rep, state senators, state rep, and local officials?
Everyone can't know everything. I doubt you do, but I wouldn't call you a fucking idiot for that. I would call you a fucking idiot for being such a small-minded asshole though. You're not the smartest person in the room, and even if you were, you still wouldn't understand how 99% of human technology works. We're in this together and we lean on each other. That's the beauty and curse of being human
