Assembly is very simple (at least RISC-V assembly is which I mostly work with) but also very tedious to read. It doesn't help that the people who choose the instruction mnemonics have extremely poor taste - e.g. lb, lh, lw, ld instead of load8, load16, load32, load64. Or j instead of jump. Who needs to save characters that much?

The over-abbreviation is some kind of weird flaw that hardware guys all have. I wondered if it comes from labelling pins on PCB silkscreens (MISO, CLK etc)... Or maybe they just have bad taste.

I once worked on a chip that had nested acronyms.

If you're interested in getting into it, download Ghidra and open an older program/game in it that you like. The decompiler is pretty amazing imo, so you rarely have to look at the assembly. But it also cross-references them so you can look at the decompiled C Code and the associated assembly. It's pretty fun 😊
