One more thing: teachers should use LLMs for grading. Grading is a boring chore, the majority of teachers hate it. Many procrastinate, and return the graded tests or assignments with a significant delay, well beyond the window where the kids are curious to see how they did. This completely destroys the feedback purpose of grading. With an LLM, you feed the scanned tests, the LLMs gives you back the graded test, and the teacher can quickly do a bit of quality control to see the LLM did not make any mistakes. If the LLM makes mistakes, then wait 6 months, there will be new version that won't make those mistakes.
