Under the category ‘information networks’, Harari puts oral stories, clay tablets, chalkboards, newspapers, computers and more. Arianrhod writes: ‘Harari aims to illustrate these dilemmas so that we … are better prepared to handle the AI revolution’. Robyn Arianrhod is an Affiliate in Monash’s School of Mathematics and the author of Vector: A surprising story of space, time, and mathematical transformation.
