If you parse the argument thus, yes, it is atomized and therefore infinite in variations of "reading PFDs, knowing sidesticks or columns, listening to the airplane, etc., etc.
But if you "gestalt" what went on over a period of about two minutes, what teases out of the background noise is the clear potential for assessing what had happened and what was happening.
One indeed can see by referring to the PFDs alone, that that is unquestionably the case. Put another way, one can rescue the airplane by reference to the PFDs.
The infinite quest is not the what or how, it is the why.
