> if the junior or medior doesn't understand matrices, nothing I do will make them understand them Oh but there are things we can do. We can add comments that link to resources, we can write long prose (both inline in comments and in out-of-band documents such as RFCs and documentation) explaining why we're using something that nobody else in the team understands vs the alternatives, and we can level people up via informal sessions like lunch-and-learns, info sharing sessions, etc. It's true that many juniors aren't capable of following concepts above a certain level of difficulty, but it's also not rare for people to really flourish if given a gentle push. There's definitely a paretto balance when it comes to knowledge sharing. Don't be that person that writes zero docs and hogs all the knowledge when you could spend 20% effort to level up 80% of people to the point where they can start helping each other.
