It's interesting how many people would not recognize assembly language if shown a sample. In a way that is a statement as to how far compilers have come, that it is possible to produce perfectly good software that runs fast enough that only a limited number of people still has to know about the details of the underlying processor.

And in the case of interpreted languages or JIT'd languages the lines get blurred a bit more but even there it is clear that whoever uses say 'numpy' does not need an understanding of the underlying operations to get through their working day.

Higher levels of abstraction translate into higher productivity, in ever more rare cases it is worth breaking open those black boxes to go to work on the underlying plumbing.
