We take up various themes from Dr. Sun-Ha Hong's latest book 'Technologies of Speculation: The limits of knowledge in a data-driven society' for discussion. The topics covered range from the way knowledge is constructed through technologies like AI to self-tracking technologies, privacy, transparency, datafication, and many others. We also incorporate various interesting questions from the live audience. This session is a must-listen for anyone interested in contemporary technologies and their quest for knowledge and prediction.     Guest Profile: Sun-Ha Hong is Assistant Professor of Communication at Simon Fraser University. Before that, he was a Mellon Postdoctoral Fellow in the Humanities at MIT. His book, Technologies of Speculation: The limits of knowledge in a data-driven society (NYU Press, 2020), asks what counts as knowledge in the age of big data, and how bodies are made into facts through the growing ubiquity of surveillance and tracking technologies.
