Welcome back to The Information Entropy Podcast! This week Tom is back and the boys are aiming to cover the topic of extinction! You will see that this is a meandering topic of cybersecurity, AI, extinction, and a section on Magic at the very end. While on topic, we find out what actually counts as extinction and how the IUCN defines and declares a species as extinct, we hear about the story of the last Thylacine, and going back in geological history we explore the big five mass extinction events.
