This week, we have a guest on the show - Rodrigo Aguilera. Specifically, we're talking to him about his book "The Glass Half-Empty: Debunking the Myth of Progress in the 21st Century". We shouldn't be happy with a narrow and limited definition of "progress" when we have the capacity to achieve so much more. But if we want to see things like the elimination of poverty, the application of human ingenuity and compassion and rationality and empathy towards solving the problems that exist in the world - this must begin with an accurate assessment of where we actually are, right now; what has led to progress in the past; and how we can get further in the future.

You're about to hear the second part of the interview, where we will dig into the flaws associated with "New Optimism" in more detail, and at the end we have a discussion about how we might hope to make the glass a little bit fuller in the future.
