Mr Parkinson's description of ATC over the Atlantic demonstrates his complete lack of appreciation of the task involved, both in such an environment and in domestic airspace.
To say that "passengers have shown their confidence in automation by boarding two-crew, twin-engined, fly-by-wire aircraft such as the Airbus A320 and Boeing 777 without hesitation" is patent nonsense. Try asking the passengers why they have decided to fly on those aircraft - I suspect most would just say that they never gave it a thought and they had no idea what type of aircraft would be used on that route.
