What's needed is an Angle of Attack indicator and a section in the QRH on power settings needed at particular AoA to maintain cruise. You dont need fancy computers to fly! Power + Attitude = Performance is how we are taught. They mentioned the difficulty in seeing the PF side stick movements but dont think any mention was made that the THS was at or close to its backstop at stall and would have needed time to get back to a sensible position to enable a recovery and the aircraft was perhaps unrecoverable by stall stage. I think Airbus got off lightly on 60 Minutes at the expense of PF and 'Systemic' problems.
