GA pilot here; I have no experience flying anything as large as a 737, but the relevant part is ... I fly manual controls (stick and rudder) with electric trimmers. Forces are forces, the trimmers should help you keep the controls at a force level that the regular pilot can still move it in normal flight. A fly by wire is the best solution for large planes with big forces on the control surfaces, but that means a re-certification program that Boeing tried to avoid. The wheel in the cockpit that pilots manually turn, no longer belongs there. It is like power steering on a large truck: you need it and it should be there. AOA sensors should be helpers, should notify or alert, but never make decisions.
