If the technology is infinitely advanced, why do we believe it would obey us? Would you obey the commands/directives of protozoic slop, or even a mentally disabled early primate? We would depend instead on the AI deriving a morality that benefits us on its own. But why would the morality that an AGI derives, based on nonhuman thinking, in a more complex and alien worldview than we can possibly comprehend, align with our own extremely narrow, frequently inconsistent values? It's not a matter of cognitive biases or misunderstanding. The idea that a sufficiently intelligent AGI would just decide to enslave itself for humanity's benefit is extremely common and extremely odd to me.
