Naomi Klein’s new book, Doppelganger: A Trip into the Mirror World, delves into what she calls the Mirror World—our destabilized present rife with doubles and confusion, where far-right movements playact solidarity with the working class, AI-generated content blurs the line between genuine and spurious, and so many of us project our own carefully curated digital doubles into the social media sphere. Klein delivers a revelatory treatment of the way many of us now think and feel, in this conversation with Jarrett Martineau from our 2023 Festival.
