An eloquent statement and I think very true.
Newcomers somewhat insult the past, give it short shrift, misrepresent
it, in a bid to stand out and seem special.
One might ask: how could one expect to do justice to the past in just
a short introduction?
That's a weak response.
On the other hand, I do believe, based on interviews with real adults,
that many get through the early math years with a great deal of
emphasis on memorization.
They memorize trig formulae, step by step ways of doing. They don't
derive on the fly. They remember.
If one is blessed with a fantastic memory, and some are (I empathize
with your own difficulties where memorizing languages is concerned),
there's a tendency to rely on that gift to whatever extent possible.
That Japanese sport I was reporting about awhile ago, of adding
multi-digit numbers in one's head, having seen them flash by, takes an
ability to visualize an abacus and work it quickly in the mind's eye.
The brain processes these sums at photographic speeds, far exceeding
the ability of a key presser to key it in, i.e we have no way to
compete with these brains once you factor in the slowness of keying or
optical scanning (but then the evangelicals would stack the deck by
having the numbers "already be in memory" i.e. they don't see humans
as part of their infrastructure to begin with).
Anyway, to wrap it up: what's another way to contrast with the past?
I think inventing a mythological past, intentionally, is not
necessarily bad marketing.
"This is the horrible little village where they used to teach math and
now we have this wonderful way".
Keep going back to the horrible village to showcase how NOT to teach.
Mock the ineffective. Ridicule the ways you despise. But it can be a
