One of the ideas of data-oriented design (of which ECS is ostensibly associated with) is that data storage and application logic should be decoupled. E.g. your logic may be organized as an object-oriented "scene graph" or whatever which under the hood transparently queries data from (say) a columnar store. It's not clear from the article how Godot entities are organized in memory or if there is even is an abstraction layer between logic and data.
