I see these ideas in a lot of data-oriented-design literature and it always struck me as needlessly reductive. Maybe it's useful to set the scene and provide a "cold shower" to get you out of an OOP-abstraction state of mind. But aside from that it seems about as useful as an engineer saying "look around! everything is made of atoms! engineering is fundamentally about moving atoms!" Which is not wrong, just not really going to help actually do any engineering.
