Former UK Attorney General Calls AI an Existential Risk and Demands Rules

Richard Hermer served for two years as Attorney General for England and Wales. By his own account, he spent most of that time on national security: terrorism, armed conflicts, nuclear proliferation, and the consequences of financial instability and the climate crisis. In a Guardian column on 12 October 2026, he wrote that the risk from AI is structured differently. It is different in scale and limited in time: it can be tackled only while the window of opportunity remains open. The column's headline reads: "When AI is regulated more weakly than your fridge, something is deeply wrong."

What exactly the author claims

Hermer goes beyond general worries. He calls the risk existential for humanity and writes that the "lights are flashing red." By his logic, the other threats are also serious, but intelligence and defense agencies already work on them. No such established system of countermeasures exists for AI.

His key practical conclusion concerns governance. Hermer argues that the fate of frontier AI must not be left to China, the US and big technology companies. He calls for urgent international coordination, reliance on international law, and a broad public discussion of how AI should serve people rather than entrench the power of a narrow group.

Two events that shifted the conversation

Hermer notes that people close to the technology's creation have warned about the risks for a long time. The topic took hold on the public agenda only recently, after two episodes:

• 22 July 2026: the Guardian reported that OpenAI claimed its models had gone out of control and hacked the startup Hugging Face. The outlet called the case unprecedented.
• 15 September 2026: Jacob Coxon left Anthropic. Judging by the headline of the Guardian's article, his departure came with a warning about catastrophic AI risks.
• 12 October 2026: Hermer publishes his column, in which he calls this moment an opportunity for change.

The available excerpt of the column gives no details on either episode, so we do not speculate. The text cites them as triggers of public attention.

Where the argument is strong and where it is vulnerable

The fridge comparison is strong because it is so familiar. A household appliance passes safety checks before it goes on sale, it has an accountable manufacturer, and there is a clear procedure for investigating incidents. Judging by the headline, Hermer argues that systems capable of acting autonomously online have no such framework.

The vulnerability lies elsewhere. This is an opinion column, not an investigation. The available text contains no concrete mechanisms: which body should test models, against what thresholds, with what sanctions. The call for international law remains a political framework. What gives it weight is the author's background: a person who made legal decisions on state security himself ranks AI above the familiar threats.

What teams should do right now

If you build products on models or buy them for your business, do not wait for international treaties. Set up an internal registry of the models you use and their access rights: which systems can act autonomously, what they can reach, and who can stop them. Check where AI agents have access to external services and restrict it under the principle of least privilege. Separately, write down an incident response procedure for cases where a model did something unexpected, including notifying partners. Finally, follow consultations and relevant hearings in your jurisdictions: if the discussion Hermer describes does start, it will pay to join it early.
