REST:
I am afraid that if they do an effort, they will overcome any obstacles, invent new systems, methods, redundancies, combined remote control and self contained systems...
Imagine an airplane that is transfered from one air traffic controller/remote pilot to another. In the event of loss of comm, TCAS will intervene. If WX ahead this can be done in a similar way.
All this research can be very expensive, let alone implementing it. But still the greedy bastards in the industry may calculate that they will have benefits in the long term, if they manage to put us out of the cockpits.
Microburst, no doubt that it can be done. But on a very small scale. By the time this is accomplished on a scale large enough to encompass the majority of the world's civil air traffic we'll all be retired.
Take FANS for example. This is something that has been on the cards since the early 90s - a good 15-years down the road before a workable system is in place (CNS - CPDLC/RNP/ADS...). Something that much more complicated as dedicated flight control inputs via remote control on a very large scale for that matter.... you just do the maths. Quite possibly our children might have made it to Senior Capt when it happens. Relax...
