Sorry gentlemen, cannot agree.
If common sense does not enter into the picture, then pilots are not needed, and Curruthers will have his automated (no pilots needed) crew.
GPWS alert below MSA, yes indeed, action required. GPWS alert well above MSA, and all concerned can agree on the aircrafts position, then action as needed, which may indeed mean continued approach. To blindly say....the box is always right...is nonsense, IMHO. Now, IF one crew member says..."something not right here" then action is indeed necessary.
My opinion anyway. Others will more than likely disagree, but have found that many just will not accept reality. These boxes installed are AIDS to navigation, certainly not the last word. That position is reserved for the respective fleet manager.
