My wife and I started talking about this after she had to help an old lady at the DMV figure out how to use her iPhone to scan a QR code. We're in our early 40s.
I feel this is very similar to working on a car. Back in the day they fixed those things up until they crumbled to dust. Pretty much EVERYONE'S dad knew how to do at least a little something on the car. But I didn't. The car was just a tool, not a hobby, my dad would fix things when they went wrong and sometimes I'd help and learn a bit, but other than that, I had it repaired or tagged it for a new one.
Cars were always there and easily accessible, but I had to learn DOS to play video games! Computers are now our dad's cars.
