Better steer clear of QF then. During complex emergencies we are trained to use the auto-flight system as much as possible..."unload" yourself so you can tend to the problem.
We can all fly engine out approaches etc. if we couldn't we'd be shown the door.
Managing a scenario well, is often critical to a successful outcome...hence your comment

...has me gobsmacked. Would you like a surgeon to have "a good pair of hands" but have no idea what he's cutting??!!
A professional aviator needs excellent systems knowledge, without which he/she is nothing more than a professional passenger. It really does help to know how the fuel system works (saves gliding to the Canary islands), what inputs the ADC's are getting (767 lost in South America), what happens when you depressurise the Yellow (or 1-2-3-4) hydraulics or de-power a #3 electrical bus. etc. etc.

I'm trying to think of a case where this could happen. Failure of six independent systems while not impossible is *extremely* unlikely.
Control cables/hydraulic lines can also be severed/freeze/rupture on non-FBW types. (I've personally had a runaway trim on
a Metroliner)
Again unlikely, but I'll still go to work tomorrow with this knowledge and that Engineering (at least in Oz) do a splendid job in maintaining the airframe and systems so that none of the above happen.
As for "not being in control"....
It is true in FBW pilot inputs are filtered but in doing so, the A380 FBW system provides high speed, low speed, bank & pitch, g-loading and many other flight protections...making it *really hard* to stall or stress the airframe in any way at all.
In many dynamically unstable military types they have to be FBW, otherwise you'd simply loose control.
As to whether this is preferable in a public transport aircraft to a non FBW system.... that will literally allow you to tear the wings off....I'd be happy to let the fare paying punters decide.
