Although they were not just hand flying. They were hand flying at a moments notice in IMC with faulty instrument data in a highly complex system. That combination of factors does seem to be a huge risk factor for accidents. I wonder if reverting back to pilot control is really the best approach in situations with faulty instruments. Perhaps it would be safer to use algorithms that can deal with bad data in a sane way. A middle ground between blindly trusting bad data (as in 737 max) and reverting to the pilot. Use other data like GPS, accelerometers, strain sensors ,fuel flow rate sensors, to sense check the primary instruments.
