The Stepford Wife has its appeal when your options are modern anything. A copy of a person is never the person. Im sure the uber rich should know as much. My guess its a cover for advancing AI in the race to create a personal machine god. That brain technology you speak of is old. Real old. We have advanced so much since then. The new tech which shouldnt even be compared to the old teck. Both the new and old teck has been used on humans many times over. Of course its advertised as anything but attempts to eventually fully understand and enslave the mind.
