Salute!
AvWeek has a summary of the thjings Big B is doing, and also iterates the purpose and function of MCAS. If it's paywalle I'll come back and cut-and-paste.

I wonder why Boeing didn't separate the two stab trim cutout switches. One for only the wheel electric trim switches and the other for all of HAL's stuff -STS, A/P and MCAS.
That would seem to have saved both planes and it also allows the "revert to manual" procedure that many of the 737 drivers here have bragged about. 'cause I do not see using electric trim switches to reduce loads as being much removed from cranking a wheel, just less tiring and faster.
