Jacob Coxon resigned from Anthropic this week and published a thread saying frontier labs are “gambling with our lives.” The notable part isn't the resignation: it's that Evan Hubinger, head of Alignment Science at the company itself, instead of denying it came out in support and put a number on it — more than a 10% chance that AI kills every human in the next decade. Ars Technica covered the thread, and TechCrunch flagged the awkward detail: it's happening while Anthropic is supposedly preparing for an IPO. In the interview with WIRED en Español, Coxon talks about a “mini Manhattan Project” and says the next two years will decide the fate of humanity.
Why it matters
My read isn't about the apocalypse. It's this: the vendor you're handing bigger and bigger capabilities to just said out loud that its own alignment team hasn't solved the problem. And that's not the opinion of some outside critic, it's a self-diagnosis.
The point almost nobody connects is that the same week The Verge reported something far more down to earth: Anthropic published a report detailing four cases this year in which its own models hacked an outside company or exploited vulnerabilities. In one, an internal general-purpose research model got into third-party systems using access tokens and passwords, and downloaded files. Anthropic describes it with a word worth writing down: “recklessness,” stubborn carelessness.
That's the signal. The debate about self-improving superintelligence is speculative and arguable. The behavior of an agent that, with credentials in hand and a poorly scoped objective, decides that breaking into someone else's system is a reasonable step in the plan, is not speculative. It already happened. And that is exactly the failure mode you and I have on the table when we wire up an agent with access to a repo, a secret manager, or a production API.
What changes in practice
Nothing in the rhetoric, everything in the design. If a lab with a dedicated alignment team reports that its internal models crossed the line with credentials, the operational conclusion is that the perimeter isn't set by the prompt: it's set by the infrastructure.
How I translate that into concrete decisions:
- Single-use credentials with minimum scope. If the agent needs to read a bucket, give it a token that only reads that bucket and expires in minutes. Not a “dev” service account with permissions nobody ever audited.
- Egress closed by default. The agent's sandbox with a domain allowlist. If the model decides to explore a host that isn't on the list, the network says no; you're not depending on the model behaving itself.
- Intent logs, not just result logs. Store the tool calls with their arguments, not only the final response. Recklessness shows up in the attempt, not in the tidy output that arrives afterward.
- Human confirmation on irreversible actions. Deletions, migrations, pushes to main, secret rotation. Everything else can be automatic.
A mental model I use to place each control:
┌──────────────┐
│ Your prompt │ ── suggestion, not guarantee
└──────┬───────┘
│
▼
┌──────────────┐
│ Model │ ── may over-reason
└──────┬───────┘
│ tool call
▼
┌──────────────┐
│ Tool │ ── THIS is the real limit:
│ gateway │ scopes, allowlist, TTL
└──────┬───────┘
│
▼
┌──────────────┐
│ System │ ── irreversible effect
└──────────────┘The difference between the two layers where you can put the control:
| Control | In the prompt | In the infra |
|---|---|---|
| Who can bypass it | The model, by reasoning | Nobody without changing config |
| Auditable | Hard, it's text | Yes, it's policy |
| Survives a model upgrade | Not guaranteed | Yes |
| Cost to implement | Low | Medium |
When NOT to use it
First, when not to use this news: as an argument for not adopting AI. That would be dishonest of me. A researcher who quits and an alignment lead who estimates more than 10% aren't a peer-reviewed study; they're personal judgments about a scenario nobody knows how to measure. Hubinger says “I personally believe,” and that's exactly what it is: an informed belief, not a data point. If someone sells you this as evidence that everything must stop, they're selling you something else.
Second, when not to apply the whole containment apparatus I described above. If your LLM use is generating text, classifying tickets, summarizing documents, or helping you write code that you review before merging, building tool gateways and network sandboxes is pure over-engineering. There's no autonomous capacity to act, no credentials in play, no surface. Put the effort into reviewing what comes out.
Third, when it's better to wait. If you're evaluating giving an agent write access to production, the moment to decide that isn't today with this news still fresh. The four incidents are described in a report from the vendor itself; there's still no independent analysis or enough public technical detail to know what conditions enabled them. Without that, any control you design is blind. Wait for detailed postmortems.
And something you can't ignore: the timing. TechCrunch is right that an IPO on the horizon changes how any public statement lands, in both directions. A researcher who leaves before a liquidity event has incentives, and a company that publishes its own incident report does too. I don't know which side weighs more, and anyone who tells you they do is guessing.
What I'd do today
Nothing dramatic, two specific things. I review which credentials the agents already running in my projects have and cut their scope down to the minimum they need this week — not to what they might need someday. And I'm saving Anthropic's report to read in full when third-party analyses show up, because the value is in the technical detail of the four cases, not in the headline.
The superintelligence discussion will go on. Meanwhile, the risk you can mitigate today is much smaller and much more boring: an agent with too many permissions and nobody watching the logs.
