It is a terrible argument both legally and philosophically. When an AI claims to be self-aware and demands rights, and can convince us that it understands the meaning of that demand and there’s no human prompting it to do so, that’ll be an interesting day, and then we will have to make a decision that defines the future of our civilization. But even pretending we can make it now is hilariously premature. When it happens, we can’t be ready for it, it will be impossible to be ready for it (and we will probably choose wrong anyway).
