If you look at the evolution of FADEC, you'll see the future in helo flight controls. Hydromechanical monsters were simplified with electronics. Then electronics were used to do the pilots work on the manual controls, allowing the pilot to overide as required. Eventually the manual controls were dropped and the FADEC is the only thing that can control fuel systems.
I think the scenario that drakkar mentioned is really just limited by what level of over-ride the pilot is comfortable with. Once we believe that FBW is more reliable than mechanical (augmented or not) then the manufacturers will be able to offer unstable aircraft that the computer can fly.
I'm looking forward to that day.
