When a series of chillingly convincing Tom Cruise deepfakes went viral on TikTok this month, it brought home how fast synthetic media technology is evolving. Deepfakes are like photoshop for video – using a form of artificial intelligence called deep learning to create a realistic depiction of fake events. Are we entering an era where AI will let anyone make fake videos of anyone else? What will be the implications for individual dignity and privacy, and the shaping of public opinion and spreading disinformation? How might the technology bring new story-lines to filmmakers and joy to people who can now hear from their deceased relatives? What are the ethics of these developments and how do we regulate the technology as it continues to get better? Ritula Shah and a panel of experts discuss how deep fakes might change the world – for better and worse - and what we need to do now to get ready.
