But having been exposed to it once, it's amazing how quickly the knowledge comes back when you need it. I did advent of code over Christmas and when the 3D transformations came up I thought about it for a bit, then remembered... something about matrices... linear algebra..? And then searched for the resource I needed to refresh myself on it. Just the fact I was exposed once a decade ago means I was able to refresh myself in a few minutes.
