OpenAI could watermark the text ChatGPT generates, but hasn't

That’s a huge problem now, though, as there are no reliable ways of detecting LLM output. Teachers are running student papers through software that promises to detect LLM writing which a) doesn’t do that, often, and b) is full of false positives. As for SEO scams, if Google (et al) detect that every page of a website has these indicators, they can pretty safely downrank it. Is watermarking a perfect solution? Obviously not, but it is a solution that works better than what currently exists.
