The internet removed consequences. You can say the most vile thing imaginable to another human being and… nothing happens. No social cost, no awkward eye contact at the grocery store, no reputation hit in your actual community. Just a dopamine hit and a notification count.
Cars did something sneakier. We spend hours every week sealed in a metal box, alone or with the same people. No random encounters, no friction with people who think differently. Just you, your podcast, and whatever is important in your tiny echo chamber.
Put those two together and you get people with deeply held morals and zero framework for applying them to anyone outside their bubble. Ethics requires seeing strangers as real. We've engineered that out of daily life.
