Likewise.
A few seem concerned about having autonomous flight control surfaces, but have pilots ever been concerned about the yaw damper fitted to the aircraft they fly? The yaw damper is automatic and transparent to the pilots. It just works.
Any system should be properly developed, test-flown, and engineered. If a system has NOT been properly developed, test-flown and engineered - for example the Boeing MCAS - problems can arise.

Yes, fair comment.
One would hope this system is fail-safe, unlike the MCAS.

The problem with MCAS is that it wasn't considered to be a flight critical system - it was assumed to be a 'major' system, and developed and certified accordingly. Had MCAS been recognized as a flight critical system it would never have been implemented the way it was.

FBW is a flight critical system - Design Assurance Level A (DAL A) - and is developed and certified accordingly.
