The religion of Calculus (growth, interest rates, etc) kills off way more mathematic joy than pedagogy. I agree with Spengler. Mathematics is not something that progresses from falsehood, or lack of understanding, to truth. It mirrors our social values. We value economic growth, we worship calculus. We value physical counts, we do arithmetic (or algebra).

Your view of the place of mathematics in society is, sorry to say, a bit, well I won't say it. You know where I'm going.

Math was never alive. And it is never dead.

You might watch the Botez sisters and Anna Cramling, etc. in chess. They have brought chess back into interest, not by focusing on all the "chess" but how it can bring people together in a common pursuit. I never saw that coming! Perhaps your daughter can make math more interesting to more people, sorry, fellow boomer, it ain't gonna be us ;)
