This is the first of a 3 part series on chapter 9 of David Deutsch's "The Beginning of Infinity". Chapter 9 is titled "Optimism" and the week this is published marks the 50th anniversary of the first steps taken by humans on the moon. If we choose to continue to pursue solutions in an open ended way - if we choose to embrace what might be called "Deutschian Optimism" then next it can be Mars...and after that the stars.
