I could make exactly the same assertions about assembly language (I learnt 6502 when I was a kid, and dabble in 6502 and 68k these days for fun, keep meaning to learn ARM). Being able to reason at that level, and read generated ASM (x86 ugh) is an invaluable skill which I use daily, and it's a level below C.

But, lines of assembly language professionally written: 0.
