I've never needed to use anything beyond pip in my 9 years of programming (science, ML, back-end web development). But maybe things get bad when you move beyond those things.
But we'll agree python's dep management is leagues ahead of javascript and R, though. Right?
Python has neither standard tooling (de facto nor de jure), has no consensus within community where everyone seems to invent their own yet-another-dependency-management-tool and no culture of preserving strong backwards compatibility (never mind the core 2->3 transition).
