I felt it quite a while back (more than 10 years ago), when, in high school, I learnt LaTeX and discovered Beamer. I naturally proceeded to make all of my presentations with it, including the rehearsal for a big competitive French exam. The person reviewing the presentation advised me to dirty it up a bit, otherwise nobody would believe that my father wasn’t a PhD researcher that did the work for me.
That was a bit saddening honestly. I kept the presentation as-is as I didn’t knew how to willfully screw up a Beamer presentation, and I would not touch PowerPoint (fortunately the final jury believed me).
Cheating had always been an issue before LLMs, but now we’re back to the same old tricks: just make sure to add a mistake or two to hide you copied the homework on your neighbor. It’s a shame because I kinda like learning the subtleties of foreign languages, and as a non-native English speaker, it’s quite rewarding when going online!
