Mowgli
Better drive a carburetted automobile then. It would be scary to have a computer 'interpret' your throttle demands. Or would you prefer it if your conventional throttle cable snapped just in the middle of that tricky overtaking manoeuvre with the 40-tonne truck bearing down?
Had it occurred to you that conventional flying controls can be jammed?
The F/O on this occasion reacted as he was trained and isolated the offending sidestick. (Yes all you sceptics - what if the Capt had, say, a seizure at the controls at the same moment on takeoff, his arm locking on his sidestick? I'm sure all A320 operators at least introduce this idea during training)
