I don't see how this was a result of complex automation or software appliances interfering with the captain and first officer's ability to fly the plane. The investigation concluded the flight was recoverable until just five seconds before impact. The plane was in full manual flight configuration well before impact. The captain failed to keep the first officer inside the control loop by failing to call out what he was doing and as a result the first officer made the situation worse. The captain stopped giving callouts in response to his perceived frustration with the control tower and the commands they gave.
