I don’t think things have changed that much. I have been fixing things all my life for people who didn’t want to try. I have seen kids that will take apart a new toy to see how it works. People who tinker with stuff are born that way and will try to take apart anything given to them. Most like me started when they got their first rattle. I repaired a toaster when I was in first grade. They were a lot more fixable item around back then. Back when electronic stuff had discrete parts you could find smoked parts and replace then. I got my a metal finder with a bad diode in the rectifier bridge. Less than a dollar in parts to repair. And parents were more likely to let you blow out circuit fuses. When I was in Jr High I took apart my saxophone and put it back together.
Some people learned how to repair stuff because they had to. And some people repair stuff because it is there.
