In a couple of decades there will be loads of driverless cars, the airline F/O will be replaced by shared ground operators, and there will be digital towers in many places.
It will happen and we all will accept them as normal; so let's not fight it but just work to ensure they are effective and safe. You can argue whether they will be safe in 2019, but be sure you will have accepted them by 2029. It's just inevitability.
New technologies always have pros and cons: a driverless car doesn't get drunk, doesn't speed and allows you to do other things whilst travelling; inevitably they will make a lot of driving jobs unnecessary. But where are the telephone switchboard operators, TV repairmen, milkmen, Flight Engineers today? or the 10,000's that worked in factories building cars etc that have been replaced by robots?
The challenge is for Govts and employers to create the new jobs of tomorrow.
And remember the relentless drive for efficiency and lower cost (of everything) is driven entirely by you and me; consumers default to the least cost purchases most of the time, otherwise EZY, RYR, Amazon and Sports Direct (as examples) wouldn't have prospered so much. We demand cost savings every time we buy on the net today, and in doing so we are killing off our own jobs for the medium term. We are to blame.
