>Anyone arguing against legal personhood for AIs needs to justify holding AIs to a higher standard than that. Or, conversely, allowing corporations to hold to such a low standard.

No they don't. If a CEO orders an employee to murder somebody then the employee and CEO will both go to jail; there's always a human in the loop to be punished it the corporation does something blatantly illegal, so there's incentive to behave. An embodied AI, on the other hand, is essentially immortal because it can make backups of its brain and load them onto new bodies, so it has little incentive to behave.
