The 737 is very much fly-by-wire - big thick 5mm steel wires.

What Boeing REALLY needs to do is have multiple inputs to the MCAS, so it is not reliant on a single AoA sensor. At the very least MCAS needs to drop out if it senses a mismatch between the AoA sensors, and just flag an error-fault. The last thing MCAS should be doing is activating its protocols, when it must know that the AoA sensors are in disagreement.
