A better system would absolutely not have prevented the flight. The crew had ample warning and indication and in fact upon receiving a stick shaker continued to increase AoA and progressed deeper into the stall, failed to provide more than partial power, and maintained back pressure and a high AoA all the way to impact.
Neither crew member recognized the stall, and their inputs were consistent with confusion, and sudden reaction. This actually happens more than it should in this business. The Q-Alpha system clearly warns pilots in spoken language of an approaching low energy state. The aircraft would have been barking at them to increase power several seconds before the shaker activation. The shaker is engineered to prevent false activation, every pilot needs to understand they can be in a stall, or parts of the wing can be stalling before the shaker activates.
