> It's funny how we drill the idea that everything must be reimplemented from first principles into students

Where on earth did you go to school that you couldn't just call list.sort() after your first algorithms class? I've never seen a class that teaches students that everything must be implemented from first principles. They only do that for the concepts taught in that class, or 1-2 classes prior, to make sure you are actually learning and have a clue what you're doing. Which... should makes sense? You should want engineers to cut costs based on understanding rather than ignorance.
