Perhaps not the best metaphor for exponential (speaking figuratively)
growth -- an artillery shell eventually intersects the sphere of the
earth (unless, of course, it was initiated with escape velocity).


Agreed.  I was positing the possible double confusion you drew attention
to -- the inappropriate curve of the ballistic parabola being conflated with
the sound of the intended word hyperbola to produce "gone parabolic".
