Three Anthropic researchers have publicly raised serious concerns about the possibility of advanced AI causing catastrophic harm, according to Axios. Their warnings came as AI developers continue racing to build increasingly capable systems.
Anthropic researcher Jacob Coxon said many people developing AI privately believe the technology could potentially kill humanity before the end of the decade.
Scalable-oversight researcher Samuel Marks similarly warned that AI could cause human extinction within years, adding that senior employees often express greater concern.
The report noted that OpenAI leaders have also acknowledged growing AI risks. Critics argue such warnings could encourage regulation favorable to major AI companies. Still, the concerns are drawing attention from policymakers as models become more powerful and potentially capable of self-improvement.
