42 Royal Society Fellows Including Fields Medalist Gowers Warn AI Extinction Risk Is an Emergency
Forty-two Fellows and Foreign Members of the Royal Society, led by Fields medalist Timothy Gowers, have co-signed an open letter to Society President Paul Nurse expressing "extreme concern" that AI could cause human extinction within this decade, calling it an emergency and urging that severe AI risks be treated as such.
Confirmed
- The letter states that estimates of roughly a 10% extinction probability "should not be dismissed as hype" and warns against waiting until the risk becomes obvious to the public before acting.
- Multiple sources report that 42 Royal Society Fellows and Foreign Members, including Gowers, jointly wrote to President Paul Nurse urging that severe AI risk be treated as an emergency.
- DeepMind's Boaz Barak shared the letter and argued the focus should not be on competition over AI capabilities (per @MilesBrundage's repost).
- Reposting, Luke Muehlhauser noted that leading mathematicians, including multiple Fields medalists, view the widely cited claim of a ≥10% probability of AI-caused extinction within a decade not as hype but as a genuine emergency (per @birchlse's repost).
- Reposter @tak3sh8 added that data points suggest mathematicians are markedly more worried about AI than many other groups, e.g. assigning over 10% doom probability within a decade.
Why it matters
- Mathematicians are known for caution and quantitative rigor; their collective statement substantially boosts the credibility and urgency of AI existential-risk concerns among scientists and the public.
- A formal letter to a leading scientific body like the Royal Society may push the scientific community to engage more actively in AI risk governance and policy debates.
