The key point I would make about regulating deepfakes is that, in some cases, new laws may be needed, but much of the harm deepfakes cause is covered by existing laws, or could be covered by amending existing laws.
Synthetic audio means that it will be possible to make any person say anything, making it even easier to make politicians or celebrities victims of deepfake as there is a lot of publicly accessible audio of their voices.
Despite alarmist news stories about deepfakes heralding the end of democracy or truth itself, the technology – for better or worse – is far from perfect, which suggests that there is still a window of opportunity to prepare society, institutions and regulatory frameworks for the moment it is.
Rhetoric about the ‘end of truth’ plays into the hands of people who already are saying you can’t believe anything – and that is neither true of most audiovisual material, nor true yet for deepfakes. We should not panic but prepare instead.
