A machine that adds, edit, or removes a person’s personality. First, the EEG would scan a person’s mind and they, including the one working on it, would see their personalities. The one working on it would ask the subject if they want to add or remove a personality, whether it’s a personality they don’t like or a personality they want to experience. Most of the subject’s personalities are printed on a printer to show a before and after. It can be reversible if they don’t like the changes.
