You seem to be hung up on the part about "learning". Do you know how x86 registers work? Or atomic instructions available on ARM, SPARC, or POWER architectures?

No, of course not. Because all of that got abstracted to higher-level instructions decades ago.

In a world where there are endless things to do and only limited time to get them done, not every issue needs to be a learning matter.

Learn what? The thing the tool can do instantly? Take the win and spend your energy on bigger problems.
