It's a common sentiment that others don't know how computers work. I'm sure you personally are an exception, but I think that most people with this sentiment live in glass houses and don't realize how little they understand about how computers work. Since I don't know how they work, I can't provide comprehensive examples, but I remember being surprised by details around dynamic linking and relocatable binaries, around how vfs maps to more specific implementations, the implementation of hard disk drive firmware, the on-drive caches and the firmware that runs that, the implementation in terms of magnetic polarity for storing bits, and many more layers and details besides that I have yet to discover.

No of course I don’t know everything and there’s lots I used to know but have forgotten.

But I do feel fortunate that I got to see a lot of the modern abstraction come into being so I have a vague idea of what they’re abstracting and why. That helps a lot.
