Quick Summary

Jacob Coxon, a researcher with 3 years of experience in pre-training research at Anthropic and OpenAI, has abruptly quit his job, warning that AI "could kill us all by the end of the decade". He claims both companies are racing towards creating self-improving superintelligence without acting responsibly. According to Coxon, executives and senior researchers are privately expressing fear about the technology's potential dangers, but downplaying it publicly. Coxon resigned from Anthropic, alleging that the company is engaged in a "hubristic gamble" by prioritizing being the first to develop AI over solving its alignment issues.

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.
