I wanted some of you to elaborate with me on this difficult subject. For those of you who do not know what sentience is, it is the ability to perceive or feel things. Of course we are talking about an artificial being which can "feel" or portray emotions. But would this just be an elusive and cunning way of the robot's programming bringing out those emotions? How would we even know if it was actually acting on a true emotional level, or if it were just to be mimicking them very well? What would we look for, and how would we look for it? And when would it be safe to say, "Okay, now it is actually acting upon it's own will, so therefore it is showing it's own individuality"? The real question at hand is how do we actually code emotions and implement them into a robot. Perhaps neuromorphic engineering is the way to go. Neuromorphic engineering is an interdisciplinary subject that takes inspiration from biology, physics, mathematics, computer science, and electronic engineering to design artificial neural systems, such as vision systems, head-eye systems, auditory processors, and autonomous robots, whose physical architecture and design principles are based on those of biological nervous systems. Ethics are also a huge issue to be programmed in a robot. And could be quite catastrophic if it decides it doesn't like us. How much "free will" should we allow them to have? And to what extent should they be allowed to feel emotions? Or should they have any at all? If a robot in the near future becomes indistinguishable from humans, do they deserve rights like we do? I personally think it would be really cool to build a robot brain based on philosophical concepts that deal with the five main branches of philosophy. Which are: Metaphysics- Study of Existence. | What's out there? Epistemology- Study of Knowledge. | How do I know about it? Ethics- Study of Action | What should I do? Politics- Study of Force | What actions are permissible? Esthetics- Study of Art | What can life be like?
