"If all goes well, the history of humanity is just beginning.

The Earth will remain habitable for hundreds of millions of years more - long enough for millions of future generations; long enough to end disease, poverty, and injustice forever; long enough to create amounts of flourishing unimaginable today. Yet humanity lacks the maturity, coordination, and vision necessary to avoid making mistakes from which we could never recover.

Thus, in the next few centuries, humanity will be tested: either it will act decisively to protect itself and its long-term potential, or, in all likelihood, this will be lost forever."
