Finally, 2020 is behind us. It changed our world, the way we live our lives, and how we relate to each other and to ourselves. Shruti Rajagopalan and Alex Tabarrok join Amit Varma in episode 206 of The Seen and the Unseen to take stock of the year gone by, with each of them picking five lessons they feel 2020 holds for us. Because they can't count, though, they end up with more than 15 -- here they are, below. (Listen to the episode for the elaborations and arguments.) The Lessons: 0. Don't take anything for granted. (Amit) 1. Don't make the mistake of Omission, Commission, Distinction. (Alex) 2. We should pay more attention to tail risks. (Shruti) 3. Art and Entertainment can be intimate and personal. (Amit) 4.

Software is eating the biological world. (Alex) 7. Science is not the problem. The problem is economic illiteracy. (Shruti) 7.5. We should move from collectivized decision-making to respecting individual choice. (Alex) 8. We need to rethink education. Not just the delivery of it, but how we think of education itself. (Amit) 9. A bigger problem than state capacity is state will. (Alex) 10. Politicians don't always behave in a rational, self-interested way. (Shruti) 11. Politics is driven only by tribalism. (Amit) 12. The internet is even better than we thought. (Alex) 13. Markets don't solve everything. (Shruti) 14. We should worry more about computer viruses. (Alex) 15.
