I've read up on ECS thrice now, (but never used it because I don't do games) and I really WANT to like it, and I feel it does have value in other domains. But... I realize every time that I forget what an entity, component and system really "is" (i mean to be fair the naming is almost satire of genericness), and the abstraction doesn't stick to my brain in a way that I had hoped. Kinda similar to how monads don't stick, and fades away over time (if you're not doing FP). Usually, this is a red flag for abstractions, but perhaps the material I've read has been poorly written. Does this feeling go away when you're used to it? Does it just feel natural and obvious after a while?
