Above we considered the very real possibility that we're the only high-tech civilization in our Universe. Let's spend the rest of this chapter exploring this scenario, and the huge moral responsibility it entails. This means that after 13.8 billion years, life in our Universe has reached a fork in the road, facing a choice between flourishing throughout the cosmos or going extinct. If we don't keep improving our technology, the question isn't whether humanity will go extinct, but how. What will get us first--an asteroid, a supervolcano, the burning heat of the aging Sun, or some other calamity

We cannot explain the choices that history makes, but we can say something very important about them: history's choices are not made for the benefit of humans. There is absolutely no proof that human well-being inevitably improves as history rolls along. There is no proof that cultures that are beneficial to humans must inexorably succeed and spread, while less beneficial cultures disappear. There is no proof that Christianity was a better choice than Manichaeism, or that the Arab Empire was more beneficial than that of the Sassanid Persians.

The less we are convinced of our exceptionalism, the greater ability we have to understand and contribute to our environment, the less blindly driven we are by our own needs, the more clearly we can appreciate the needs of those around us, the more we can appreciate the larger ecosystem of which we are a part.
