There is something I don't get about ECS and DOD when it comes to performance, maybe twitter can help. It is often used as an argument that looping over game objects is faster, because you only loop over the data you need and they are lined up in memory (1/2).

But how often do you loop over all game objects? At least in my engine I use spatial queries for pretty much everything and keep active/passive sets. What is a realistic use case? (particles systems don't count. particles aren't game objects)

To me, the cool thing about DoD is that it's statically analyzable & you can schedule across cores/machines/whatever. Other benefits from static analysis besides automatic threading. I'm a fan of rendergraphs for the same reason and feel they are strongly related informally.
