To me the issue seems to be whether we want pilots to fly an aircraft by playing a computer game, or whether we want them to fly an aircraft according to the laws of physics.
It seems pretty clear that the AF pilots were doing the former rather than the latter. The basic difference between the two is that with the computer game, it is the computer's instructions and feedback that are your "law." The stall warning starts to sound, this means that the aircraft is approaching stall. Placate the computer by pulling nose up and the stall warning stops -- the computer responds by telling you that you are playing the game "correctly." Note that although these pilots were likely trained to understand that the computer game has other "rules," such as keep an appropriate speed and attitude, the computer states that the stall warning has priority over all these other rules -- so you don't address them until you've dealt with job #1, silencing the stall warning.
In contrast, flying the aircraft according to the laws of physics tells you that if you are in a severe nose-up attitude with less than 60 knots of airspeed at FL 370 (or even any two of these three conditions), you are in stall. These laws also tell you that in an A330 weighing over 400,000 lbs. with a maximum of 140,000 lbs. of thrust, you cannot climb out of a stall as you might with an F-22. While AB software engineers have done wonderous things with FBW, they have not repealed Sir Isaac Newton.
Now I don't know enough about A330 maneuverabilty to know whether once the stall was entered, it was recoverable, but shouldn't these guys have known that nose-up had no dynamic hope? Or were they just expecting that the FBW computer would find some deus ex machina way of extracting them from this dire situation?
In fairness, AB should certainly change its stall warning protocol to make more clear when it is inhibited because of unreliable airspeed. And I guess it may also be possible that the accelerations in the cockpit made it impossible for the pilots to gain any situational awareness. But the tapes seem to suggest a relatively nonviolent descent into the ocean. In the end, it all comes down to what you can rely on. These pilots relied totally on the computer, and were willing to suspend any belief in physical law.
