I’m shocked how many otherwise well-informed people don’t understand or agree with this very fundamental fact of just how little we actually understand about why LLMs work as well as they do. They figure “it’s science, of course there’s math and theory behind it.”

AI research is almost as purely empirical as the gradient descent loops its practitioners use to optimize their models. “Why” anything at all works is barely an afterthought.

Well-informed people understand that LLMs work as well as they do for the same reasons as horoscopes, fortune-telling and homeopathy.

That's a very different claim from being "poorly understood" though. The emergent properties of any system with billions of parameters is hard to understand completely, that's the fault of data science more than computer science or even mathematics.
