Ben Fischer is a Marshall scholar who graduated from Stanford University, and is now at the University of Edinburgh studying the technical and social implications of privacy preserving age assurance. He had a chance to sign an open letter from a group of scientists, calling for a moratorium on age assurance laws globally. He chose not to sign it. In this episode, he explains why.
