This episode is highly visual and better viewed on Youtube here: https://www.youtube.com/watch?v=VlcQ4ZFKrKk However, the substance is still there in this purely audio-only version. This is another episode not primarily about "The Beginning of Infinity" but it is deeply inspired by it. It is a discussion exploring the "resources" debate. Are resources finite or infinite? I look at the intersection between economics and cosmology or people and the universe. So this is all about how knowledge changes physical reality, or as David Deutsch has said: how explanations transform the world.
