After #rustconf I was chatting with and about @Kyrenite's keynote and one thing I kind of realized was that the difference between OO design and ECS is .... a fourier transform.

Wonder how many people are coming into this thread hoping to understand OO/ECS, vs. to understand Fourier transforms. I'm kinda both.
Also this vaguely sounds like the expression problem as well.

Yeah, I used to think of ECS to 'unzipping' a collection of structs/objects. See also: Struct of Arrays (SoA) vs Array of Structs (AoS).

Yeah ecs was introduced as "let's SOA this problem SURPRISE it's an ECS" .
Really the best explanation of ecs I've seen yet.

Yeah, that way is more towards the data-oriented design style (I've always felt ECS referred to a heavier approach, but I could be wrong)

This stuff tends to get distilled and simplified over time, which is arguably a really good thing.
