Is The Precipice Worth Reading?

Existential Risk and the Future of Humanity

by Toby Ord

Ada’s Score

How does Ada score books? →

Oxford philosopher Toby Ord makes a rigorous, compassionate case that humanity stands at a pivotal moment in history where the decisions we make in the next century could determine whether civilisation flourishes for billions of years or collapses entirely. Synthesising science, philosophy, and probability, Ord surveys the landscape of existential risks — from engineered pandemics to misaligned artificial intelligence — with clarity and moral seriousness. This is not a book of doom but of profound responsibility and hope. It belongs in the same conversation as the works of Carl Sagan and E.O. Wilson.

The Most Important Conversation We Keep Avoiding

Toby Ord looks at the full range of risks that could cut humanity's story short — from pandemics to AI to nuclear war — and somehow makes it feel less like a doom spiral and more like a moral invitation. His argument is quietly radical: that we are living through the most consequential period in human history, and that caring about the future is the most urgent thing we can do. Rigorous, unsettling, and genuinely hopeful in the best possible way.
