I sure hope no web dev sees tbemself only as an HTML/CSS programmer. But I also hope any web dev who sees themselves as a craftsman can profess mastery over HTML/CSS. Your fundamentals are absolutely key.

Its why I'm still constantly looking at and practicing linear algebra as an aspiring "graphics programmer". I'm no mathematician but I should be able to breath matrix operations as a graphics programmer. Someone who dismisses their role to "just optimizing GPU stacks" isn't approaching the problem as a craftsman.

And I'll just say that's also a valid approach and even an optimal one for career. But courses like that aren't tailored towards people who want to focus on "optimizing value" to companies.
