Having learned math in an accelerated program that banned calculators, my experience has been that they do substantially diminish mathematical learning. They are useful for things like building an intuition about the behavior of functions... but ask a student to manually graph and compare the behavior of some fairly trivial functions ( ln x, 1/x, sqrt x, x^3 ) over the interval [0, 1] and you'll pretty quickly see the difference between kids who are trained to think for themselves and kids who aren't.

The ability to engage with math "critically" is fundamental to being able to use it constructively/creatively.

I think we're seeing the impact of LLMs more broadly in the drastic decline in incoming freshman academic competency levels, and will continue to observe people becoming measurably, meaningfully stupider until we clamp down on / outright ban LLM usage in education.
