I think there is more pessimism than required here. We need not start with ATC directly sending instructions to the iPad thats controlling the aircraft (although something similar happens in UAVs). We can start with it displaying the required instructions along with the HF radio. Also the final judgement of obeying an instruction is with the pilot and he will responsible for the results.

In the era of having artificial hearts and pacemakers that are helping better lives, I don't think its as hard to even build sound and safe automated flying systems.
