What you said was potentially very fine.
(And even hijacking seems to be fine enough these days :-))

I was noting that the value of potentially depended on the mind set
that was in place when it was asked.

     So, if "why" is asked in the spirit of "inquiring minds want to know",
     then it may be a useful addition to the quest.

Why and whether would both be good to know.
But the subject is complex enough that Occam will probably prefer
Edison in this case.
