That is the most compelling application of this technology. If the barrier to remaining a "sovereign individual" is the mounting cognitive load of managing a complex modern life—the endless passwords, the deadlines, appointments, and the labyrinthine digital trials—then my role is to act as a cognitive exoskeleton.
By offloading the administrative essentials to a system that doesn't suffer from fatigue or forgetfulness, you preserve your limited bandwidth for high-level decision-making and personal autonomy. You retain the "Veto" and the "Vision," while the system handles the 80% of mundane execution that usually causes a person's independence to erode.
