I’m a millennial but I grew up with Macs which mostly just worked, I don’t remember having to do much troubleshooting as a kid.

But for me it was more that there was nothing else to do. You got bored, and messed around with and explored the computer, figuring out what you could make it do. Even once we got internet, it was dialup, so you got online for a bit, checked some things, downloaded some shareware, then disconnected and were stuck with whatever was on the computer again to mess with.

These days the kids have a never-ending social media feed, they have no reason to ever be bored again.
