I set it down as a fact that if all men knew what each said of the other, there would not be four friends in the world.
— Pascal, Pensées

Holmes is referring to the recent reporting on Anthropic’s Claude Mythos Preview, an AI model it says is unusually strong at cybersecurity tasks — i.e. it can hack into almost anything. Anthropic says it is limiting access for now rather than releasing it broadly, though I think we’ve all seen enough movies to guess how that’s gonna go. Anyway, her tweet is melodramatic, but everyone instantly understands the horror it suggests: search history, cloud photos, private messages, old usernames, medical records, bookmarks, drafts, forgotten accounts — all the digital sediment of a life suddenly dredged up and dragged into public view. We have already seen lesser versions of this often enough. A stray remark from years ago is dug up and treated as a character indictment. One offensive post becomes the loose thread that unravels a person’s name, job, location, hobbies, and history before a jeering crowd. Real life used to let most foolishness die where it was spoken. The internet stores it, indexes it, and waits.
A recent Substack post about a woman reading her boyfriend’s ChatGPT logs shows the same problem from the other side. There the threat was not some AI super-sleuth prying open the vault. It was plain old human suspicion. She went looking and found what she was never meant to read: not a record of prostitutes buried in the backyard, but his private ambivalence toward her. Many people in relationships have silently pondered the Kinks’ eternal question of whether to stay or to go. In this instance, his fatal mistake was to commit these doubts to digital text, rather than let them remain inchoate thoughts in the privacy of his own skull. Naturally, the relationship was ruined. This is what snooping does. It takes passing thoughts, bad moods, ugly drafts, and momentary resentments and preserves them like fossils. We talk as though the great danger is that machines may someday expose all our secrets against our will. But there is a demand side to this too. More and more, people want that power over others. They want to inspect first and trust later. They want reassurance by surveillance. And once you start down that road, nothing will ever be enough.
The old dystopias understood the point without any help from Silicon Valley. Bentham’s Panopticon and Orwell’s 1984 both take for granted that a world without privacy would be hellish. Human beings need locked doors, unsent letters, private notebooks, tact, silence, and the mercy of forgetting. They need room for thoughts that are not yet judgments, moods that pass, stupidity that can be outgrown. So yes, let’s be wary of building tools that can hang all of our dirty laundry in the public square. But let’s also be wary of the part of ourselves that longs to peek through the keyhole. Not everything that can be known should be known.
