Holly+ gave a voice clone a constitution. The consent tools that followed settled for an opt-out box

In July 2021 Holly Herndon released Holly+, a voice instrument trained on her isolated vocals, with a plan for token holders to approve official uses and share the money. A year later she and Mat Dryhurst co-founded Spawning, whose "Have I Been Trained?" opt-out became one of the most widely used opt-out tools in AI. The first idea asked permission up front; the second asked artists to object. Five years on, the first is still the better template.
