Well, looks like the GP missed a very common false fact:

The operations written in a program must literally represent the operations the computer will execute.

This one stops being true on high-level languages at the level of x86 assembly.

Exactly. A MOV is reduced to a register rename. An intelligent compiler can rewrite multiply/divide by 2 as shifts if it makes sense, etc.

"Assembly is not a low level language" is my favorite take, and with microcode and all the magic inside the CPU, it becomes higher level at every iteration.

True. :)
