But we already have multi-generational non-person entities: companies. Copyright may be assigned to companies instead of persons. They are just registered under a bunch of people's names, which act as owners (shareholders), and can change over time. In the future, AI entities will probably be registered as companies themselves (or maybe they will be just company assets), and will be owned by people. Which doesn't bode well for strong AI, but I suspect that even after we reach strong AI people will still grasp at straws for many decades or centuries, denying them personhood because they are just software that run on computers.
