I don't agree. These are factual claims and should be treated
as such. By the way, who said that the hyperreals of Robinson are
shorthand notes? And on what evidence?

Except for the bit about newer guys being smarter and the fact
that things AREN'T better BECAUSE they're new, the progressivist
has it pretty much right, at least for mathematics. It's not that
new things are better, more progressive, but rather that, among
the new things, we value mainly those that ARE better. Or rather,
it's not the new things alone that matter but how they contribute
to the picture as a whole. That's what we want to be better. E.g.,
when Robinson published his book, that was a new contribution that
enriched our picture of mathematics, making it better than the one
that preceded it.
