In reality, it's more like this: https://en.wikipedia.org/wiki/Blind_men_and_an_elephant https://en.wikipedia.org/wiki/Blind_men_and_an_elephant Software is so huge that it would take you a lifetime of programming from different perspectives to get a grip on what it really is. So we are all doomed to experience POSIX through whatever programming experience we end up getting deep in. I feel the underlying problem most software is that it's just too damn complex, so you can't fit enough of it in your head to design it how you think it should go. An average person can't go "Oh, I think the kernel should be able to do this" and then go whip it up and having an experiment running in a little bit. That's an esoteric corner full of tons of specialized and arcane knowledge that, truth be told, is completely invented. And half of that invention is workarounds for other bad inventions. I dunno enough to just pronounce doom on POSIX, but I do feel like the rickety C way of doing things (everything centered around intricately-compiled machine code executables, incredibly dainty fragile eggshells that shatter and spill their entire guts of complexity on the world) underpins a ton of the problem. The number of years you would need to just read, let alone grok all the hundreds of millions of lines of code that run on our system is just beyond human lifetimes now.
