Quick Summary

Paul Christiano, an AI researcher and co-author of a 2016 paper on AI safety, has expressed concerns about the potential for human extinction due to uncontrolled technological growth. He now sees "meaningful risk" of catastrophic loss of control in the near term, warning that most people could die. This aligns with comments from other experts, including Geoffrey Hinton, one of the founders of AI, who estimates a 10% risk of human extinction. Christiano has joined OpenAI's nonprofit safety team to address these risks.

Story summary

On September 8, Jacob Coxon, a 27-year-old researcher who previously worked at both OpenAI and Anthropic, resigned from Anthropic, warning that the companies are racing towards developing self-improving superintelligence and potentially putting human lives at risk. Coxon's resignation drew significant attention online and in media outlets like CNN and BBC News, with experts such as Geoffrey Hinton estimating a 10% chance of AI causing human extinction within this decade. Notably, several current Anthropic employees echoed Coxon’s concerns on social media platforms, emphasizing the urgency of addressing AI safety issues before it is too late. Despite these warnings, some in Silicon Valley and industry leaders remain skeptical about the immediate threat posed by AI advancements.
