But we are not the public we are pilots on this forum so I think we can judge. Even a humble PPL like myself can see why it all went wrong.
The engines are to far forward due to their diameter so at high AoA they generate lift so the centre of lift moves in front of the centre of gravity so the nose will keep pitching up.
So the real solution is to fit longer undercarriage legs and move the engines back no MCAS needed. But at unimproved airports without special high lift support vehicles
would make it difficult to service. The MCAS could have worked with a little more thought into failure modes, should have been more fault tolerant and customers should have not have been able to delete multi channel AoA sensors just to save a few dollars and better pilot training for trim runaway on all 737s because manual trim loads can be so high it can be impossible to manual trim.

My humble thoughts.
