C programmers usually don’t feel it in their guts either how computers work. The amount of code transformations modern compilers do to make C performant is really mind-boggling. Though to add a more relevant point, I read a great saying on HN that a good developer knows their stack. A great one knows a layer beneath as well. (I usually butcher up quotes, sorry. It may have been more layers actually)
