I’m an external examiner for CS students and around 90% of the subjects we test them in is stuff they’ll never use in the real world.

It’s obviously anecdotal but in several decades or real world work I’ve never heard the words composition and aggregation used, and I’ve frankly never seen them really implemented intentionally in code either.

I sort of feel the same way with things like linked lists, double linked lists, trees and so on, though I see the value in those, but not enough for them to take up half a year of learning along with various sorting algorithms.

I have no idea to balance the “useful to know” with too much theory though, but I do know that almost everyone who graduates is around a years worth of real world coding away from being a programmer.
