What if the doomers and skeptics are both a little bit right? O ne 27-year-old quit his job, and everybody (including but not limited to the singer-songwriter Sheryl Crow) appears to have lost it.

AI safety advocates, often dubbed doomers, have been saying this for over a decade.

Jacob Coxon published the viral post from a park bench in San Francisco's Alamo Square. "I resigned from Anthropic today," he wrote on Sept. 8. "I spent the last three years doing pretraining research at both OpenAI and Anthropic. Neither company is acting responsibly. They are racing straight to self-improving superintelligence and gambling with our lives."

US President Donald Trump has downplayed the need for his administration to place checks on artificial intelligence development, saying he is worried about ceding the US's lead to China. Speaking to reporters during his trip to Ireland on Sunday, Trump also said he acknowledged the need for some regulation but did not provide further details on potential measures. "We can put guardrails, we can do this and that, but I think you have a lot of negative forces that are bringing it up that shouldn't be bringing it up, and they're bringing up things that won't happen," Trump told reporters after watching the Irish Open at his resort in Doonbeg. He said that with the US leading the development of AI over China, "frankly, I want to keep it that way because whoever wins AI wins." Trump's comments came a day after Anthropic CEO Dario Amodei published a blog post saying the AI industry must slow the pace of improving the technology's capabilities to allow time for guardrails.

AI staff'genuinely frightened' for humanity's future, ex-Anthropic researcher tells BBC To play this video you need to enable JavaScript in your browser. Figure caption, 'There is a possibility of human extinction,' former Anthropic employee says about AI An AI researcher who quit Anthropic told the BBC that people working on the technology are genuinely frightened about the speed of its advancements and what it could mean for humanity. Jacob Coxon spoke with BBC's Laura Kuenssberg on Saturday about his viral resignation post where he raised concerns about out-of-control artificial intelligence. I believe that if we don't slow down at the current rate of progress, there is a strong chance that we could all die in the immediate future, he said. His resignation comes amid growing safety concerns in the industry, including from his former boss, head of Anthropic Dario Amodei, who in an essay on Saturday argued for development to slow down.

Each September, a who's who of executives from across Silicon Valley descends on San Francisco's Palace Hotel to charm investors at a conference hosted by the investment bank Goldman Sachs. This past week, between talk of growth and potential returns, tech titans found themselves addressing the abrupt resignation of Anthropic researcher Jacob Coxon. Coxon, a 27-year-old who worked at OpenAI before joining its chief rival Anthropic, said on Tuesday that people building artificial intelligence (AI) believed the technology could destroy humanity. They are gambling with our lives, he said, these will soon be superhuman systems that can hack anything. Coxon is by no means the first AI insider to publicly sound the alarm.

Anthropic AI claims to have thwarted multiple malicious operations using its Claude models, ranging from cyber-espionage and weapons design to mass surveillance campaigns. On the conventional weapons front, the company alleges in a new report that it intervened in northern Yemen, blocking an effort to deploy Claude for missile guidance software, including a guided rocket and a long-range ballistic missile. According to Anthropic's threat report, the operators used Claude "in place of human software engineers", reportedly assigning different instances of the model specific roles to write missile-guidance and flight-control software. While internal safeguards blocked many requests, Anthropic admitted several slipped through. The operators avoided detection by obscuring their ultimate goals and breaking tasks across separate sessions, so no single prompt gave away the operation.
