A critical difference between a calculator and an LLM is that a calculator doesn't make decisions. A calculator performs the operations you type in, nothing more. An LLM does make decisions. The human operator of the LLM needs to be able to evaluate the decisions made by the LLM. That requires education and experience beforehand.

An LLM is a force multiplier only, not a replacement. It's a personal assistant to an expert. To use an LLM in a acceptable way, you still first have to learn how to do what it does yourself. I think your suggestion for people to be taught how to use LLMs is justified, but they should do so only after first being taught a no-LLM curriculum. I think this should be entirely after what the notion of an education was in pre-LLM times. Don't incorporate LLMs into our current education, instead teach use of LLMs after our current education.
