If you think of the hardware as a black box, it does correspond to the instruction set architecture presented. Generally you don't think about implementation details of an op-amp when you wire it into a circuit. The issue is that CPUs have become so complex that the lines are blurred, since the external interface is so removed from what's going on inside with micro code and ooe and cache. So while pedantically there are no longer low level language outside of microcode, that renders the term useless, and I'd prefer the natural language evolution that's occurring.
