Machinery in the Star Wars universe seems to be aware to an extent. Why? What’s the threshold? If I just build a head is that enough? If I just build a torso, is that enough? What about Luke’s cybernetic arm? It seemed to act of its own volition on a couple of occasions.

There’s an issue with cross pollination, too. Maul’s upper half was attached to a crawler droid and he thought he was some cave spider. 3PO’s head was on a battle droid body and he started developing a bloodlust for combat.
