Do we need to distinguish between Atlas, the control theory based humanoid tech stack vs say Optimus that may run on an end-2-end visual reasoning world model?

Do we need to distinguish between Atlas, the control theory based humanoid tech stack vs say Optimus that may run on an end-2-end visual reasoning world model? I feel these are two different paradigms. Same for military drones. The next gen prototypes may have launch-and-forget levels of autonomy, however ethically questionable.
