I have been trying to think of ways we could leverage digital signatures to prove that something isn't AI-generated, and it's really a fascinating topic to think about. It's hard to avoid making the leap from "this isn't AI generated" to "this exact person made this." Then there's the issue of ensuring that a person doesn't make ChatGPT write something, then copy and paste it somewhere else and sign it.

If anything, the hardest part of making an anti-AI proof system is ensuring people don't lie and abuse it.
