Part 10/12:
The discussion ends with the matter of whether we are alone in the universe. Vijay leans toward the pessimistic view that Earth might be uniquely inhabited or that intelligent life is exceedingly rare, due to the "Great Filter"—a once-necessary barrier that prevents civilizations from reaching interstellar levels or self-destruction.
He emphasizes that if we are indeed alone, it makes Earth's life even more precious, underscoring the imperative to protect and sustain human civilization. This includes plans to seed life on other planets—sending bacteria, plants, or even human life—to preserve life’s essence throughout the universe in case Earth becomes uninhabitable.
