Techtonic is a new podcast from human rights organisation Article 19, hosted by tech reporter Chris Stokel-Walker and produced by Christopher Hooton and Nicola Kelly. The new series looks at freedom of expression online with a focus on the human impact of Big Tech and social media. We speak to experts around the world, including the former Head of Elections at Twitter, digital rights activists and journalists and we hear from those at the sharp end of AI, deepfake technologies, internet shutdowns and more.
