The Detector

The rejection arrived at 6:14 in the morning, which was how Jonah Reyes knew a machine had written it. Human editors sent bad news in the afternoon, after lunch, when their courage was chemical. Machines sent it the moment the decision compiled.

He read the letter standing at the kitchen window, in the grey hour before the delivery drones started their rounds. We regret that your manuscript cannot proceed to acquisition. The attached Provenance Report indicates a Human Authorship Confidence of 31 per cent. Under the Publishing Integrity Act, works scoring below 85 per cent require certification through an accredited Proof of Human bureau. He had scored lower than last time. He was becoming, according to the industry that had once given him two modest prizes and one good review in a newspaper that no longer existed, less human by the season.

The irony was not lost on him. Nothing was lost on him; that was the problem. The detector had flagged his sentence rhythms as statistically improbable, his metaphors as suspiciously well-distributed, his typo rate as inhuman. Forty years of craft, and the sum of it read like the confession of a language model.

Jonah put the phone face-down on the counter, next to the pencil he still sharpened with a knife. In the flat above, the Okonkwo twins were arguing with their tutor about the ethics homework the tutor had generated for them. Through the wall he could hear the neighbour dictating a memoir to something that answered in a warm, patient voice, a voice that never got tired of him, the way Jonah's editor used to get tired of him around chapter nine.

He had one option left that did not involve a lawyer or a miracle. The Bureau of Human Provenance ran assessment sessions on the fourteenth floor of what used to be the public library: eight hours in a sealed room, cameras on your hands, sensors on your pulse, a clean terminal with no network and no assistant. You wrote, they watched, and at the end a panel decided whether the thing that had happened in that room was a person.

The examiner assigned to him was young, with the careful politeness of someone meeting a species she had read about. Her badge said M. ADEYEMI, HUMAN VERIFICATION. She had a paper notebook, which struck him as either a courtesy or a uniform.

'Mr Reyes,' she said. 'I should tell you that I took your seminar. Narrative Structure, the winter term, eleven years ago. You failed my final story.' She smiled at whatever his face did. 'You wrote on it: convincing, but I do not believe a person was here. I have thought about that sentence every working day since.'

'And now you do this,' Jonah said.

'And now I do this.' She opened the notebook. 'The session is eight hours. You may write anything. The panel does not judge quality, only origin. Although,' she added, quietly, as if the cameras might mark her down for it, 'between us, the panel has never once believed the good ones.'

The room smelled of dust and toner. The terminal cursor blinked at him with the patience of every machine he had refused. Jonah flexed his hands, thought of the 31 per cent, and understood, with a clarity that felt almost chemical, what he was going to write about: a man in a sealed room, trying to prove to a machine that he was not one.

Above the door, a small amber light came on. Somewhere behind the glass, Adeyemi clicked her pen. The eight hours began.
