The accident is not caused by failure of A/T TOGA mode; it's caused by the PF not shoving the thrust levers forward when the A/T didn't or was too slow. Manual inputs are elementary and instinctive anytime the automatics are not performing as they should. During any approach, in any airplane, irrespective of A/T operation, whether autoland or not, the PF must always keep one hand on the thrust levers.
