At two in the morning, somewhere in this country, a college student is hitting submit on an essay she wrote herself. Every word is hers. By breakfast, a piece of software will hand her professor a percentage saying a machine wrote it. No hearing, no cross-examination, no appeal. Just the number, and the number is confident, and confidence is the whole product. I have spent the past year writing a book about that number. It is called Swimming the Author. It is out now, in paperback and on Kindle, and the title comes from the oldest confidence machine on record. In the seventeenth century, when a woman in England was accused of witchcraft, one way to test her was water. They bound her, thumbs to toe, and lowered her into a pond. King James himself supplied the theory: the water, being pure, shall refuse to receive the guilty in her bosom. So if she floated, the water had rejected her, and she hanged. If she sank, she was innocent, and she drowned proving it. The pond could only convict. That is the machine. Everything since has been a redesign.
