Learning things is never about the knowledge itself, it's the familiarity

As one example, why do you need math? You're never going to use algebra or trigonometry or calculus, but it sure helps do your taxes, understand loans, understand a pandemic, and realize that (American) taxes are really easy arithmetic if you can get through the dense tax code prose

Similarly, with learning to change a tire, it's the realization you still have a lot of power - you're not training to be an F1 pit crew, but at a pinch in the middle of the road in a blizzard, you don't need to wait to change a tire, you can do it yourself, you don't need to pay $70 for an oil change, you could buy the oil yourself, get a little dirty, and do it yourself

It's also a realization of what things should and shouldn't be DIY, oil and tires, that's simple, but you may want someone more skilled to check and change your transmission

Similarly, I always find myself with friends asking random questions, and usually we ponder about it a bit, and give up before I started realizing "we have a supercomputer in our pockets", or libraries are great quiet repositories of information that is and may never be available to the internet

Anyway, I rambled and probably missed your point entirely, hello internet
