Yes. On labelling, there are a bunch of ways to go about it. We're agnostic as to these technical paths, but certainly it's something that could be developed as a global standard. For example, the Internet protocol that helped the Internet happen is a global standard. It's the same thing with labelling. I've heard proposals, for example, of having Unicode, basically the language behind the text, be labelled as AI so that a computer would automatically know if a letter is written by AI or not. There are a lot of solutions like that, for example, that could happen.
Ultimately it's probably going to take some government impetus to force these companies to actually do it, because it will be a pain to actually label, and there will always be the challenge that even if you label a piece of text, somebody can take a photo of it and copy it over to another computer, and now suddenly it's no longer labelled.
It's the kind of thing where you can't.... Labelling won't stop misuse in that sense, but it can, if you catch somebody using AI that isn't labelled, give you an opportunity to take action. It's not a full solution on its own, but it's a step in the direction of giving incentives for people to actually use the AI correctly.
