Re: The software isn't the main problem
I think you're right about how the force changes, I was over simplifying. The problem was that although it was initially a minor fix, it ended up having to be significantly increased, I think the trim movement was about 8 times larger than originally planned. It also inexplicably had full trim authority, which is what led to bad things happening.
I would disagree that panic and inexperience were to blame, the pilots in the first crash didn't know MCAS existed so they wouldn't have known they had to remove its effects. The pilots in the second crash did know about it, did what Boeing had said would solve the issue, and then found themselves unable to control the aircraft and unable to manually trim it due to aerodynamic forces. Slow round of applause for Boeing introducing an emergency procedure that doesn't solve the problem.
