In my opinion, most articles, lessons, etc. that purport to teach assembly miss the forest for the trees. This is a good article for someone wanting to learn "what assembly _is_" - but I have yet to see an article targeted to programmers that would teach "how do I practically use this."

One can learn the vague syntax complexities, etc. - maybe even write a Hello World..but without having real-world exposure of what compilers actually do to source code, people cannot actually derive meaningful signal or intuition. A very experienced programmer without exposure to assembly might be able to optimize a tight loop or spot a performance issue, but that's probably the extent of it.

Complexity increases as you introduce platform-specific calling conventions, APIs, etc.

I don't know a better way to acquire assembly intuition than by implementing a RISC-V CPU or staring at a lot of decompiled output.
