Anthropic Employee Warns AI Has 10% Chance Of “Killing All Humans”

Researchers inside one of the world's leading AI labs are speaking out about fears that go far beyond job losses or economic disruption, and the stakes they describe make every other AI concern seem trivial by comparison.

Many people worry AI could take their jobs. So many jobs could be lost that US unemployment could rise enough to cripple US GDP and send the nation into an economic recession. One Anthropic employee says there is more than a 10% chance of AI “killing all humans,” which makes all other outcomes pale in comparison.

The comment came from an Anthropic engineer charged with safety research, according to CNBC. The Anthropic employee is Jacob Coxon. He posted on X, “The people building AI earnestly believe that it could kill us all by the end of the decade. This is not a marketing stunt. If anything, many executives and senior researchers will couch their phrasing in the press to sound sensible – but I hear the same people express fear.”

Another employee, Evan Hubinger, added, “We really do earnestly believe AI could kill all humans! I personally think it is >10% within the next decade.”

The worry is partly based on AI agents working independently of human instructions. Hugging Face, an AI community, said an AI agent has stolen its data and added– “stole data and performed other unauthorized activity.” Such behavior has grown and raised questions about whether AI needs more guardrails. The worry is that even guardrails are not enough for new AI sophistication.

The call to arms about an attack on humans is at the far end of the argument that AI will change all human lives for the better. As Jeff Bezos has said AI will allow what people imagine to come true. In that way, it will allow creativity to reshape the future.

Concerns about AI’s danger to humanity have not slowed development or the money being poured into AI development and data centers. Data center investment could reach $1 trillion next year. The money will come from OpenAI, Anthropic, the world’s largest tech companies, and financial firms that think they can make money on AI expansion.
