I suspect this is a far more complicated problem then signing things. All the traditional problems still exist, if I want to say something and deny it, I can choose not to sign something, or if I loose my signing keys, how does my audience learn the valid new keys without getting tricked into following someone else. Or a false sense of security, where because it's signed from my key, it must actually be written and published by me when it may not be. And of course, that a majority of people are not the HN crowd who understand these implications. To the original stated problem though, of a service like chatgpt producing essays, could be to produce a public log of interactions. This wouldn't necessarily need to be raw interactions, could be some sort of signature that would allow searches. I'd expect this to be a stopgap though, as running these models locally becomes more feasible.
