all I can hope for is that a new industry or reliable ecosystem of vetters of real human talent will emerge. Are you really as good a writer as you claim to be? Show us the badge. That or AI firms have to be forced to 'watermark' all their creative outputs, and anyone misleading the public/audience should be punishable by law.
Both are just mid-summer dreams. There is no global law to enforce watermark. There are no badges that can't be forged.
