I’m a teacher and the last half of this school year was a comedy of my colleagues trying to “ban” chat GPT. I’m not so much worried about students using chat GPT to do work. A simple two minute conversation with a student who creates an excellent (but suspected) piece of writing will tell you whether they wrote it themselves or not. What worries me is exactly those moments where you’re asking for a summary or a synopsis of something. You really have no idea what data is being used to create that summary.
