It’s not just the internet. For example, students are handing in essays straight from ChatGPT. Uni scanners flag it and the students may fail. But there is no good evidence either side, the uni side detection is unreliable (and unlikely to improve on false positives, or negatives for that matter) and it’s hard for the student to prove they did not use an LLM. Job seekers send in LLM generated letters. Consultants probably give LLM based reports to clients. We’re doomed.
