Relying on someone's NEC program to number crunch to
produce the answer 42 is not the same as understanding
what is going on as an aid to didactification of novices.

Why is it that those who shout about NEC on the one hand, and
resort to personal remarks on the other, seem to neither have answers
nor able to contribute to discussions?

Sadly, I am reminded of those who claim that they don't need any
understanding of mathematics because of the availability of electronic
pocket calculators.
