yes, the series is a disgrace to the great foundation novels.

the emperor is the only redeeming part of it. well, maybe the trantor visuals are as well

clone yourself, always keep a kid, adult and old geezer clone at the same time

infuse your memory on them ofc

the adult they/you decides. the young and old are helping with decisions or replacement if you have an accident

that seems to be a solid foundation for a lasting empire. nobody can possibly predict this to go wrong in any way.
