They are, in fact, not still comprehensible. Don't get me wrong, you can learn a lot, but it's no longer possible to have an in depth understanding of everything going on in a modern PC. At a certain abstraction level, sure, but the subsystems are now too complicated for one person to have detailed knowledge of it all.
Okay, I used the word "possible", but perhaps I should have used the word feasible. If the information exists then it's "possible" to learn it. Although given that the hardware companies no longer actually tell us everything that's going on in their hardware, you could make an argument for it not being possible.
Well, i didn't claim i know it all. But i gave it my best because it's true that one person can't have the detailed knowledge of all the now-existing complicated subsystems.

Not with most of the terrible (i.e Lenovo, Wikipedia) information found online, It's never impossible but very unlikely.
