I think he means that you don't need to train a human to understand that a calculator is useful, and in particular when a problem is hard enough that you need to bust out a calculator. That sort of logic is self-apparent in humans, but struggles to be consistently evoked in LLMs.

That said, I was using simple +*-/ calculators as a small child and I don't think I needed to be taught anything other than MC/MR. The tool is intuitive if you are familiar with formal written arithmetic (of course hunter-gatherers couldn't make sense of it).
