Even a ground station will not be able to pull/reset a circuit breaker, for example. Or detect a rapid change of weather or circumstances.
He will always be "behind the aircraft", especially in times when he is really needed. So again, its not responsible. Possible though, but not safe.
The DC-10 was developed with remote control circuit breakers. Modern aircraft make an automatic attempt at resetting systems that fail... Progression will continue.
I have flown in aircraft with monochrome WXR displays, made more work for the pilot, today we have auto stab, colour density, vertical profile and predictive and reactive windshear. There has been progression and it will again continue. It will happen when it is safe and reliable enough to an acceptable margin.
