Through this section, Harari reaffirms that the best solution is still a global community and neither Facebook, nationalism, or religion will unite human society. Part 2 provides possible solutions to how humans might be united to confront these global issues, including whether Facebook engineers using algorithms can create a global community and whether we can reverse the globalization process and re-empower nation-states or religious traditions. Through Part 1, Harari hopes to show the urgency and magnitude of these global problems at hand.

In Part 1, Harari offers an overview of the biggest political and technological challenges of humanity’s collective lifetime.
