FO kept stealing control of the plane from the lance captain, it wasnt systems knowledge that would save them. If the fo in the left seat could get some feeling/warning the guy on the right was deepinging the stall he could have saved them. 35000 ft in the air and homeboy shoots for 15degree nose up because he sorta remembers a recovery techique for a situation they werent in.

at least a connected sidestick and the guy on the left could talk the idiot down from killing everyone.
