The Precipice

In this book, Toby Ord argues that humanity is in a uniquely dangerous period, which he terms 'the Precipice,' beginning with the first atomic bomb test in 1945.

Ord examines various existential risks, including natural and anthropogenic threats, and estimates that there is a one in six chance of humanity suffering an existential catastrophe within the next 100 years.

He advocates for a major reorientation in how we see the world and our role in it, emphasizing the need for collective action to minimize these risks and ensure a safe future for humanity.

The book integrates insights from multiple disciplines, including physics, biology, earth science, computer science, history, anthropology, statistics, international relations, and moral philosophy.
