Did Bungie ever elaborate just how Sentient the Exo are? Are they like Sunny from I Robot, Replicants from Blade Runner, or Roy Baty (and the Nexus-6's) from Do Androids Dream of Electric Sheep? Do they have feelings, emotions, dreams, and motivations? Or are they more simple than that? Do they only listen to what they are told to do, mindless robots with no soul or spirit? Or do they fall in love? Maybe my questions are to... involved but I'm curious as to how human they actually are, or like-human.
