Until Boeing fixes this it will continue to kill pax in their hundreds.
You can't blame Boeing when dangerously incompetent individuals get promoted to the left seat. It has nothing to do with any manufacturer. The 737 was thoroughly tested by experienced test pilots to a degree you would hardly believe. Nothing wrong with the autopilot engaged buttons - it is the idiots that push them. The degree of pilot incompetency is downright alarming in many third world airlines but political correctness rules OK? and that means the real truth never gets out to the aviation media. There is SFA the manufacturers can doing anything about this once the aircraft are delivered to the new owners. Same with cars and motor bikes.
The time is well overdue for regulators and operators to take a critical look at each individual up front. Religious mores and associated cultural blind belief act often in direct opposition to flight safety principles.
