Tourist,
The military use of thise drones is still limited to specialized tasks despite all that potential they have.Those drones are not replacing helicopters and transport aircraft for airlift operations now or some time in the future, because they are not capable to do the same like manned aircraft can do, they are not able to make decisions, they are only able to stick to them. Therfore there will be always fighters ( not all of them) with pilots, to make the appropriate decisions when they are necessary. If you have ever been a fighter pilot, you would know how many of those decisions have to be made on an average ride.
The crude preprogrammed decision making of computers works well in a preplanned environment with a preplanned task and with the knowledge that you can get away with unplanned losses, because its war and somebody else is paying the bill.
There are less decisions to be made in airliners than in fighter aircraft, but those which are left are important ones and might cause great harm if done wrong.
Nothing has changed since those words were said:
Aviation in itself is not inherently dangerous. But to an even greater degree than the sea, it is terribly unforgiving of any carelessness, incapacity or neglect.
How would an unpiloted airliner cope with a MEL list, with ATC and weather demands (both can't be foreseen), with inflight emergencies not in the book, with simple software and hardware bugs we encounter on a day to day basis where we are already dependent on functioning computer driven systems? There is no fail safe in live as there is no unfailable human.
The most ridiculous arguments are derived from those statistics, like 70% of airline accidents are caused by human errors. You might know, that 30% of the car accidents in Germany are caused by drunk drivers, and 70% by sober ones. You think that we should remove those 70% sober drivers or make them drink to get the highest improvement in accident rates?
