I take the opposite view but to the same conclusion. I've heard the joke "the more advanced you get the worse you get at math" from a lot of mathematicians. I'd bet most mathematicians can't do a long division problem without having to think pretty hard about it, because they've long since moved past that skill.
All that said, people still learn and do manual math at all levels in order to advance the field even though calculators and python notebooks exist.
I think people get too wrapped up in LLMs being the entirety of the future when the LLMs themselves are entirely a product of the past. An LLM is less a thinking machine than a lossy JPEG for language and to an extent, knowledge represented in language. As such, if you want to expand the field and move into the future you aren't going to rely solely on an algorithm that reverts to the mean.
