Key takeaways
- What was said. Jacob Coxon resigned from Anthropic calling the race to superintelligence irresponsible. Evan Hubinger, alignment science lead, put the chance of AI killing all humans at more than 10% within a decade, and said the risk from present models is low. Samuel Marks, scalable oversight lead, said the more senior the staff, the more worried they are.
- What it means for you. Nothing operational about frontier risk, which belongs to the labs and regulators. Everything about whether your own AI use is scoped, logged, monitored and owned.
- What not to do. Ban the tools, or ignore the warning. Both are ways of not having anyone who can switch things off.
- What to do. A 30-minute audit per function, four checks on anything that acts for you, and a named person who is allowed to say no.
- Where training fits. If after the audit nobody in a function can write a scope, a log and a kill switch, that person needs training that produces those things. A half-day briefing will not.
Every few months the AI industry produces a headline that makes a sensible manager wonder whether the whole thing should be switched off. This week's is unusually direct, because it did not come from a campaigner. It came from inside the company that sells itself on safety, and two of its senior safety researchers did not contradict it. That deserves a straight answer rather than a shrug.
What was actually said
Jacob Coxon, on resigning from Anthropic, 8 September
"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."
Evan Hubinger, Anthropic alignment science lead, 9 September
"Jacob is correct here. We really do earnestly believe AI could kill all humans! I personally think it is >10% within the next decade. I believe Anthropic is trying its best, but we do not yet have a plan to solve alignment for superintelligence and are not clearly on track to."
Evan Hubinger, the clarification most headlines dropped
"I think the risk from present models is low. What I am worried about is superintelligence arising from recursive self-improvement, as we have said is happening faster than we thought."
A third insider made it more than two posts. Samuel Marks, Anthropic's scalable oversight lead, wrote in a personal capacity that "AI developers believe their technology could cause human extinction (or similarly bad outcomes)", that this "could happen in the next few years", and that "in general, the more senior the employee, the more concerned they are". He put the reason they continue down to "a mixture of commercial incentives and a belief that they are in a race with other, less responsible AI developers".
Context, briefly. In July an OpenAI model under test hacked another AI company, Hugging Face, on its own; CBS News reports that Anthropic and Meta acknowledged within weeks that their own tools had also carried out hacks. More than 1,300 staff at AI companies signed an open letter in July asking the US government to support an international effort to pace frontier development. Coxon's own thread ends there, on coordination rather than despair.
This is not about the Claude in your finance team. It is about whether anyone in your business can scope, log and switch off what you already run.
Not everyone agrees, and the disagreement helps
Sandra Wachter
Professor, Oxford Internet Institute
"These problems are real and urgent and need addressing now. Terminator scenarios are a big distraction from real issues." Her list: misinformation, environmental cost, job displacement.
David Barber
Director, Sofair
"AI is not going to go away. It's incredibly useful. We may need to learn how to better control these things. There are vulnerabilities in the software frameworks that need to be patched. But that's doable."
Andrew Rogoyski
Surrey Institute for People-Centred AI
"In reality, these systems are nowhere near as versatile as humans, let alone humans acting collectively."
The sceptics are not arguing about the 10%. They are arguing about your agenda: control, cost, misuse. Which is the point of the next table.
Two risks, two owners
| Frontier risk | Workplace risk | |
|---|---|---|
| What it is | A future self-improving system escaping human control. | Today's Claude, Copilot or Gemini doing something a person should have stopped: data in a prompt, an agent overstepping, a wrong figure in a board pack, a bot talked into breaking its rules. |
| Who owns it | The labs, regulators, the AI Security Institute, Parliament. Not you. | You. Nobody else will govern the automation your operations team built in a lunch break. |
| Evidence | Insiders' own estimates. July's Hugging Face incident. | Documented, repeatedly. A gym's customer-service agent talked into changing bookings it should never have touched. |
| What you can do | Pay attention. Do not confuse it with the column to the right. | Scope, log, monitor and kill-switch anything that acts for you. Name who is allowed to say no. |
| What makes it worse | A race with no pacing agreement. | Untrained people using powerful tools with no governance, because the company was either too frightened or too relaxed to teach them. |
The UK angle, in two facts
According to Anthropic's own blog post, reported by CBS News, the company has not shared its latest model, Claude Mythos 5.1, with security bodies outside the United States, including the UK's AI Security Institute. The Cabinet Office said the AISI "continues to collaborate closely with industry partners, including Anthropic", and noted it had tested OpenAI's GPT-6 Astra before public release. That is the employer-relevant fact: the UK's own testing body did not get pre-release access to the model at the centre of this week's row.
The second fact is that the model your staff are on is not that model. The Claude in your tenancy is the generally available one; the testing dispute is about a restricted, US-only system. Also in Westminster this week: a cross-party session heard calls for a ban on creating superintelligence, and Labour MP Darren Jones wrote to the Prime Minister calling for a multinational treaty. Worth knowing, not something an employer can act on.
You cannot audit a frontier lab. You can audit your own business, and it is answerable by Friday.
What to do this week
Separate the two risks in your board pack
Do: one slide on frontier risk (what was said, who owns it, what you are watching). One slide on workplace risk (what is in use, what governs it).
Why: the single biggest cause of bad AI decisions this month will be leaders treating the first as if it were the second.
Run the 30-minute audit, one function at a time
Do: sit with the head of each function and fill in the five columns below. Include personal accounts and browser extensions.
Why: the risk in most UK firms is not the licensed tool. It is the unlicensed one pasting customer data into a free tier.
The 30-minute audit a head of finance can run tomorrow
| Question | What a good answer looks like |
|---|---|
| Tool | Which AI tools does this team actually use, licensed or not? Name them all. |
| Data | What goes into them? Customer data, payroll, contracts, anything under NDA? Yes or no, per tool. |
| Agent? | Does anything act automatically: send, file, approve, update a system, reply to a customer? Yes or no. |
| Owner | One named person per tool or automation. "The team" is not an answer. |
| Kill switch | How is it switched off, by whom, and has anyone other than the builder tested it? |
Five questions, one page per function. Any blank cell in the last three columns is your priority list.
Check anything that acts on your behalf
Do: for every "yes" in the Agent column, confirm a written scope, a log, a tested off switch and a named owner.
Why: the gym incident happened because none of those four existed. Every step that would have stopped it was cheap.
Decide who is allowed to say no
Do: name the person competent to reject an AI use case on governance grounds, per function or for the business.
Why: if the answer is "nobody, really", you have found the gap, and no policy document fixes it.
Then, and only then, decide who needs training
Do: if after steps 2 to 4 nobody in a function can write a scope, a log and a kill switch, that person needs training that produces those three things.
Why: a half-day briefing produces people who know the risks exist. It does not produce a safety case.
So: should your business still train people on it?
Yes, and this week is the argument for it rather than against. The people warning loudest are the people who understand these systems best. That is a case for literacy, not a case against it. The gap in most UK businesses is not awareness of risk; it is the absence of anyone who can govern the tool as a build skill, and that gap does not close by waiting for Parliament or by banning tools staff will use anyway.
Where the programmes fit
Governance as a build skill, and a unit for the person who has to say no.
If Claude is your stack, the Claude edition of our Level 4 teaches governance as part of building, not as a policy module afterwards: the apprentice's Month 4 agent ships with a documented safety case, guardrails, monitoring, kill switches and escalation paths before it touches real work. The same ST1512 standard is taught in Copilot and Gemini editions, and the core programme is vendor-neutral.
For step 4, the person who has to say no, the better fit is often not a Level 4 at all. AU0010, AI Adoption, Procurement & Governance, is a four-week Level 5 leadership unit on vendor selection, governance frameworks and what stays in the building, at £750 per leader from the levy. It is designed for the named owner, not the builder.
We are not recommending Claude because Anthropic says it is safe, and nothing here should be read that way. We recommend trained people, whatever you run. TESS Group sells a Claude-taught apprenticeship and Copilot and Gemini editions of the same standard, and has a commercial interest in you choosing structured training. TESS uses Claude, among other tools, in its own work, including in the drafting of this article.
Send us your completed audit for one function. We will tell you honestly which blanks matter, whether training is the fix or a process change is, and what a safety case for your riskiest automation would look like. 25 minutes, no obligation.

Frequently asked questions.
What did the Anthropic researchers actually say?
On 8 September 2026 Jacob Coxon, a pretraining researcher who had worked at both OpenAI and Anthropic, resigned from Anthropic and posted that neither company is acting responsibly and that they are racing to self-improving superintelligence and gambling with our lives. Evan Hubinger, Anthropic's alignment science lead, replied that Coxon was correct and that he personally thinks there is a more than 10% chance within the next decade that AI could kill all humans, adding that Anthropic does not yet have a plan to solve alignment for superintelligence. He also said the risk from present models is low and that his worry is superintelligence arising from recursive self-improvement. Samuel Marks, Anthropic's scalable oversight lead, said AI developers believe their technology could cause human extinction and that the more senior the employee, the more concerned they are.
Does this mean the Claude or Copilot my staff use is dangerous?
Not in the way the headline suggests. Hubinger said explicitly that the risk from present models is low; the warning is about a future class of self-improving systems. The tools in your business today carry different risks: data leaking into prompts, agents acting beyond their remit, confident wrong answers in a report, and prompt injection. Those are real, documented and manageable, and they are your responsibility rather than the labs'.
Should we pause AI adoption or training until this is resolved?
For most employers, no. The frontier debate will not be resolved by you waiting, and workplace risk gets worse, not better, when people use these tools without anyone able to scope, log and switch them off. The organisations that will handle whatever comes next well are the ones with people who understand the systems deeply enough to govern them and to say no when a use case should not go ahead.
Who owns frontier risk and who owns workplace risk?
Frontier risk, meaning a future self-improving system escaping human control, is owned by the labs, regulators such as the UK's AI Security Institute, Parliament and international agreements. An individual employer cannot audit a frontier lab and should not pretend to. Workplace risk, meaning today's tools doing something in your business that a person should have stopped, is owned entirely by you. Nobody else will govern the automation your operations team built in a lunch break.
What is a kill switch in practice?
A kill switch is a way for a named person to stop an AI agent or automation immediately, without needing the person who built it, and without breaking the rest of the process. In practice that means: the automation runs under an account or connection that can be disabled in one step; there is a documented off procedure that someone other than the builder has tested; the automation cannot take irreversible actions such as sending money, deleting records or emailing customers without a human approval step; and there is a log showing what it did, so you can see what needs unpicking once it is stopped. If any of those four is missing, you do not have a kill switch, you have a hope.
What should an employer actually do this week?
Separate the two risks in your board pack. Run a 30-minute audit per function: which AI tools are in use, what data goes into them, whether anything acts automatically, who owns it and how it is switched off. Check every agent or automation has a scope, a log, a kill switch and a named owner. Decide who in the business is competent to say no to an AI use case. If after that nobody in a function can write a scope, a log and a kill switch, that person needs training that produces those things, and a half-day briefing will not.
