Interesting to watch the term "brogrammer" evolve. I'm not entirely sure what it means anymore, but I do recall it was typically used for programmers with stereotypical frat boy mentalities, then it went on to imply misogynistic tendencies, then it became a sort of generic slur and now the author uses it as a synonym for "inexperienced programmer" - one who doesn't want to peak in the lower levels of the stack more specifically, lack of desire to learn in other words.

I've only ever seen the term "brogrammer" used in SV circles, though. It's hardly a phenomenon for the tech industry as a whole.

Other than that, I somewhat agree. Most of our software hasn't evolved conceptually much since the 80s, with some notable exceptions in academic and PL circles that haven't gained mainstream acceptance, predictably.
