In this chapter, they discuss the concept of immortality and how it may not be as enjoyable as it seems. They mention the TV show 'The Good Place' as an example that explores this theme. They also talk about Isaac Asimov's Foundation trilogy and the idea of psychohistory, which suggests that collective behavior can be understood even without knowing the specifics of individual behavior. They express their disagreement with this concept and explain why it is important to them.
