I'd like to think that ChatGPT 4 will be completely undetectable as a machine-generated text. We saw incredible advancements in natural language processing and machine learning in 2022, and it's not a stretch to say that ChatGPT 4 will be able to produce human-like speech that is indistinguishable from a real person. Kids are 100% already using this for essays and coursework and there's no way that educational institutions are going to be able to keep up with it. By the time they implement any stable standardised method of detection we'll be two versions ahead haha
