This idea of a human-in-the-loop whose role diminishes over time will recur with many AI related technologies. Imagine call centers today with automated attendants backed by fleets of humans to handle all the special cases and frustrated callers. This duo will remain in place, but the humans will dwindle over time, handling increasingly obscure accents and odd situations, as the AI gains capability. Until there is only one lonely human... waiting for the phone to ring. Power is handed over not with a bang.
