Hats off to @Egon@hexbear.net for their patience and trying to actually educate this commenter
From my personal experience with these people it’s more of a “I got top grades in school, especially the difficult STEM subjects which means I’m just smarter and know things about everything better than anybody else”
I’ve taken to calling this “engineer brain” but it certainly applies to more than just engineers. Math guys heard “the entire world is math” at some point and decided that since they know math that means they know everything.
