A lot of apple's design philosophy hides the technical detail, to try and create a friction-free user experience. Android does the same thing, but apple were doing it earlier and on desktop devices to some extent. Windows back in the day was significantly more transparent, although I don't know if I can say the same for modern windows

That's well and good for some things, but the concern that it reduces the natural tendency to become highly tech literate is genuine.

your car's main control unit may also be based on bsd (i have no idea whether that is in fact the case) but surprisingly most people would not call themselves experts on car electronic just because they drive a car.

while a lot of people considers themselves to be "it experts" just because they were raised by youtube instead of their parents since the age of 2.

My school system used macs before OSX and switched to Windows almost entirely when OS 9 was still the latest thing. Sounds like another user had the same experience. OS 9 was nothing like unix and had no terminal even, to my knowledge.

Apple hasn't always used a Unix-like system, though. The old Mac OS on those school computers was it's own beast.

And now it seems like schools go for either chromebooks or tablets anyway.

Where? Not in Spain. In fact no one I know was taught computers in Mac.
