I don't think this is a good idea. Also, how would you watermark text exactly? Hash all generated texts that were ever put out? Not feasible I believe and easily circumvented.

I can run a specialized AI trained to a certain domain on my laptop that reaches GPT levels and sometimes even beyond that. The work needed here is exactly what malicious actors would also invest and they would have competitive advantage.

I believe we should watch the developments, but I don't believe regulation is warranted yet.
