An eagle isn’t having a conversation with an eagle on the other side of the world about whether it should eat its prey because it’s sentient. It just eats it. I think that speaks to a moral superiority, in some ways.
I’m not claiming humans are morally superior in sum (there is a lot of evil as well as good.) But it’s pretty obvious that humans are the superior species evolutionarily in that we’ve essentially dominated the planet. And on some level, are beating evolution itself (by fixing genetic issues and helping the “least fit” to survive and reproduce.) And are also the only species which has doctors for other species.
All I’m trying to say: I can easily accept other species are intelligent and emotional. The fact that I can know that and accept that, to me, speaks to human “superiority.”
Does superiority matter? Not most of the time. What about when it comes down to life and death? If the choice was to keep one human alive or one theoretically more perfect AI alive? (Boil down utilitarianism into its essence.) doing the “most good” is by definition a human construct. Maybe an agent could have one. But if you don’t accept human superiority on some level, would you accept that a more perfect AI deserves to live more than you? To me, that’s the implication.
