I only found Drepper's paper 4-5 years ago, but it would have been a godsend back when I learned how modern computers work. It took a lot of inefficient effort to scrounge together the basics, having a single source that covers most of the essentials is immensely valuable as a starting point. Agner Fog's manuals are another piece of essential reading and reference that I recommend everyone go through at least once.

And yes, the title isn't hyperbole. You can skim the parts describing specific tooling, but the fact that the description of the memory hierarchy and how it works hasn't been internalized by every programmer is a travesty.
