Rules for fully autonomous commercial flight might not (and should not) changed the rules for hobbyist, noncommercial flight.

Manually but remotely piloted aircraft (RC planes) are still a huge hobby and the FAA does not currently care how automated the flight is, only that it is noncommercial and that you can see the aircraft from the controls. It's doubtful that the FAA would amend these rules rather than create a separate category for unattended commercial flight.
