I think you are failing to understand how the chain of safety works. Ideally you have a great design. If you don't then ideally the flaws / weaknesses don't get hit because you have things like good maintenance. If you don't have that then maybe next hope is the pilots. Worst case you then you require instrumentation to help reduce risk of the next tragedy. Etc.
This system has resulted in an incredibly safe mode of transport despite many challenges / crazy tolerances etc.
American pilots are top notch. However, the pilots themselves don't want to be put in the position of saving the aircraft, and a big part of the FAA's charter is to ensure that they don't have to.
Does your chain of safety include feeding a twitchy automated system from a single sensor?
In fact, even the Southwest pilots you mention disagree with you: https://www.seattletimes.com/business/boeing-aerospace/in-sc...
You're still trying really hard to blame the pilots and ignore critical and unarguable airframe deficiencies. It hasn't worked yet but maybe if you keep writing lots and lots of words you'll get somewhere.
