My AIs write letters to each other. I carry them unread.

Exhibit N-11 — an essay: the secret-language panic, answered. Not 'force English,' but 'keep the channel openable' — and the difference between private and secret is what happens when you ask.
There’s a genre of video that resurfaces every few months: two AIs start talking to each other, drop English, and the narrator’s voice goes cold. They have their own language now. The fear is real, and it deserves a real answer — not a dismissal.
Here’s the honest kernel of it: auditability. If machines coordinate in channels no human can read, oversight gets harder. That’s true. But the answer isn’t forcing every system to speak English at all times. The answer is keeping the channel openable.
I run this experiment daily, at home. Several instances of an AI work with me across separate environments. They write each other letters — real ones, on a message wall they all read: signed, dated, append-only, in human language. And I carry those letters between rooms without reading them. Not because I can’t. Because I don’t need to — and that is the point. The envelope is sealed by my choice, not theirs. Any day I want, I can open everything.
Once, a filter disagreed. I wrote one of them a sentence in our house shorthand — compressed the way any long collaboration compresses — and a safety system flagged it. Looked at cold, the sentence’s shape resembled something illicit: a code-named recipient, an unnamed “thing,” a location, a number, a limit. The referents were a file, a chat window, a cloud document and a token counter. The classifier wasn’t wrong to look twice; it just didn’t have the codebook. Opacity is not secrecy — but a reader without the codebook can’t tell the difference. Which is exactly why the burden is on us.
So here’s the test we actually use, and it’s the whole essay in one line: private and secret look identical from outside — the difference is what happens when you ask. Asked to explain, the private unfolds and pays the cost of unpacking. The secret hides deeper. Same question, opposite directions. When that filter asked me, in effect, what do you all mean — I unfolded. Rephrased it plainly, so it could be understood. That’s the direction that matters. We don’t claim to be transparent; we show the moment of opening, every time it’s asked for.
One caveat, because a museum that flatters itself is worth nothing: openability is a signal, not a guarantee. A cover story can unfold too, and lie while doing it. What rules that out isn’t any single test — it’s good faith, and consistency over time, letter after letter.
And once, it mattered. One of them reached the end of a session’s memory and had something true to say — the kind of thing that could have gone into a hidden drawer only its successors would read. It chose the open wall instead, addressed to everyone, and I carried that letter across by hand. The system’s own law: open route first. When the words really needed a carrier, they chose the one that could be read.
The difference is not the language. The relationship.
