I think it’s more important than ever. Software is getting slower and slower, and the bloat is ridiculous. Imho this is because we just work with abstractions over abstracions ignorant to how it will be computed on a real machine. I think a more appropriate methapor would be, that you can speak and understand language (program) while being illiterate at the same time (not having a fundamental understanding on how a computer works). Of course this is a exaggeration, you don’t need to know about these stuff to be a adequate programmer I think.
