I know some educators follow me and I have a question for you: what are you doing about the use of LLMs for essays and assignments? In a world of "plagiarism checkers" and "humanizers", presumably it's very hard to prove that students haven't done the work that they are handing in. It must be fairly obvious though. Are there moves to change how students are assessed? Or have you all just given up? Have you started using LLMs to read and mark the "work" that students claim to have done?
