Effective Altruism: Ten Global Problems – 80000 Hours One: Toby Ord on existential risks
03:13:38
Existential Risk Estimate
- Toby Ord estimates a 1 in 6 chance of human extinction this century.
- This alarming figure highlights the importance of mitigating existential risks.
Asteroid Risk Awareness
- Public interest in asteroid risks increased following the Shoemaker-Levy comet crashing into Jupiter.
- Movies like "Deep Impact" and "Armageddon" further heightened awareness and led to the creation of Space Guard.
Shared Risk Mechanism
- Several existential risks, like supervolcanoes, asteroids, and nuclear war, share a common mechanism.
- Atmospheric disruption leading to global cooling and reduced crop growth is a major vulnerability.

A New Interview in a Two Years
03:12:10 • 1min
In 2020, Oxford academic and 80,000 Hours trustee Dr Toby Ord released his book The Precipice: Existential Risk and the Future of Humanity. It's about how our long-term future could be better than almost anyone believes, but also how humanity's recklessness is putting that future at grave risk — in Toby's reckoning, a 1 in 6 chance of being extinguished this century.
Toby is a famously good explainer of complex issues — a bit of a modern Carl Sagan character — so we thought this would be a perfect introduction to the problem of existential risks.
