We aren’t really arguing about that though. When people exclame that OOP is dead, they use Java/C++ as their strawmen, but that doesn’t mean objects are intrinsically flawed or really dead. It’s like declaring you hate FP because Haskell isn’t to your liking.
My original comment was that ECS is just another kind of object system. It has objects, it conforms to ontological object thinking, why would that not be OOP? Just because it isn’t Java/C++? Or would you argue that OOD and OOP are separate things?
