AI researcher quits over superintelligence race he says could kill all humans

A senior researcher at Anthropic has resigned, warning that artificial intelligence could kill all humans by the end of the decade. The Independent and the Daily Mail both report the departure, framing it as a warning about an "out of control" race toward superintelligence.

According to the Mail, the researcher - whose work involves AI safety - has left the company over concerns that the development of superintelligent systems has become uncontrollable. The Independent frames the story around the Prime Minister acknowledging AI "risks" in the same news cycle. Anthropic, founded in early 2021, positions itself as a safety-focused AI company - the departure of one of its own safety researchers is the story within the story.

The timing matters. This is not a science fiction novelist or a retired academic raising the alarm - it is someone who was inside the room where the technology is being built, walking out and saying so publicly. The gap between "we are the responsible ones" and "even we cannot control this" is the thing worth watching. When the people building the guardrails say the guardrails are failing, the question is no longer whether there is a problem but whether anyone in the room has the authority to stop.

What to watch: whether other researchers at Anthropic or its competitors follow, and whether any government with jurisdiction over these companies treats the warning as anything more than one man's opinion. The test of seriousness is not the speech - it is the regulatory response.
