This week, we'll talk about end of the world scenarios from around the world. We'll also talk about Big Data: what it is, how it's collected, how it's used and by whom, and why it's worth understanding. We'll also chat a bit about heuristics, filter bubbles, and priorities. Let's Know Things is produced and hosted by Colin Wright. For more information about the podcast, to sign up for the LKT newsletter, or to learn how best to support the show, visit letsknowthings.com.
