Deepfakes are a new form of synthetic media that broke upon the world in 2017. Bringing photoshopping to video, deepfakes replace people in existing videos with someone else’s likeness. Currently, most of their reach is limited to pornography and efforts at discreditation. However, deepfake technology has many epistemic promises and perils, which concern how we fare as knowers and knowns. This chapter seeks to help set an agenda around these matters to make sure that this technology can help realize epistemic rights and epistemic justice and unleash human creativity, rather than inflict epistemic wrongs of any sort. In any event, the relevant philosophical considerations are already in view, even though the technology itself is still very much evolving. This chapter puts to use the framework of epistemic actorhood from Chapter 5.
