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.
