This last paragraph really gets to the nub of the problem.  Physicists
and chemists and engineers do have to use the recipes, and they do not
consciously use the understanding of the meaning of what goes into
those formulas and methods.  BC (before computers) more of this was
necessary, but the high school mathematics, universally taken by these
scientists, did not give good grades to those who could not at least
use the concepts; this is very definitely not the case today.

The recipes can, in most cases, be carried out by a clerk or a machine
without understanding what they mean.  But only an understanding of the
underlying concepts can enable the formulation of a new problem in such
a way that the recipes can be carried out.  This is what is lacking in
courses in mathematics, and especially in statistics, for people in
specified fields.  The concepts do not change, but the importance of
the various types of manipulations change.  But more and more, machines
are capable of the manipulations.
