Perhaps you'd add your aviation-based criticism of the Speed Trim system, the Elevator Feel system, and the Rudder pressure limiting system to name just three - that already exist, unremarked, on this manual flight control aircraft?
And explain why/how it is unacceptable to have safety augmentation devices in a manual control aeroplane yet you appear to believe it is perfectly OK for an entire aeroplane's control systems to be electronic? That doesn't seem rational.
How does the mechanical method of controlling the aeroplane ('manual' cable controls or fly-by-wire) have any bearing on the matter?
