Skill most people had:

• Sewing, at least basic sewing. Tailors were expensive, and if you just needed to shorten a pant leg, or fix a hole, you just sewed it. Nowadays mending clothes is almost pointless, given they’re basically made to get holes in them immediately.
• Speaking quickly to avoid collect call fees. People would call home from a hospital phone, which would charge the receiver’s bill if they accepted the call. The phone would ask for your name, and you’d say your message quickly, which lead to your parents at home getting a call from “Baby’s a healthy boy” and then hanging up.

Difference: The whole world doesn’t smell like cigarette smoke anymore. Even when I was a kid in the early 00s, it still smelled of cigarettes basically everywhere.

So y’know. We can’t sew a patch on, or speed rap to avoid collect call fees, but at least drunk driving is illegal, and we have seatbelts
