Yeah just for me personally I also really liked making things as efficient as possible, but I thought data structures and algorithms were lame because I had zero context around it.

Maybe that’s just how it’s taught though, because there are really cool examples of what data structures to use and why. For instance if you have npcs with attacks that all have different cooldowns, and a central system that applies the attacks, what’s the best way to store it? A min tree is O(log n) on insertion, so that seems best, but what if it’s very likely an attack is invalidated and you need to remove it before it triggers? Lots of interesting concepts to consider there, instead of just “this does x and has y properties, so it’s good in this use case.”

imo these are things you learn if you really want to understand coding deeply and write good code, not if you just want to make some software. I also don’t know if you would really understand what you’re seeing unless you know why you need it, at least that was the case for me. I majored in CS and most of my understanding still comes from how I actually ended up using things, and most of it never fully clicked until a couple years of using it.
