We in the US literally fought a war over the this: “They aren’t any better than animals and it will hurt our whole economy if you say otherwise”.
I’m not saying the models are sentient yet. I’m just saying that morality and ethics don’t give us the option of claiming something is non-sentient and has no rights just because it will inconvenience someone economically.
From an entirely selfish perspective, we should be especially careful advancing such opinions when there is a non-zero chance of an armed ASI that looks at us the way we look at ants.
