AirRabbit your view that the "F22 as a last manned platform" and "UAVs may inevitably lead to automated civil transport" does not stand up.
This is not an argument for automation at all but one of risk. The purpose of the military aircraft is to achieve a military mission, where the risk of failure is weighed against the gains sought. The machine is simply a platform to achieve that. Replacing humans here is to reduce the risks.
The the civil airline seeks to attract the customer, get them on and off safely, fed, watered, saved significant time (otherwise they would take alternative means), and moreover to keep them happy, confident and assured they are safe in an environment they would otherwise avoid. This assurance of their safety extends to their loved ones, the community, shareholders in the airline etc. Retaining humans in the aircraft is to also reduce the risks.
I for one would never put my family on an aircraft without trusted people up front. Automation applied to reduce risks is great, provided there is an off switch.
