Draw the draft

And for the first time that evening, nobody mentioned YouTube.… The couple’s two sons were spending the night at their grandparents’ house, leaving the apartment unusually quiet. After dinner, the husband leaned back with a glass of beer while his wife scrolled through her phone. “Our older son said something interesting the other day,” she said. “He wants to be a YouTuber when he grows up.” “A YouTuber?” Her husband laughed. “How are you raising them? Only a tiny fraction of creators make a reliable living from video platforms. And once you start publishing, there are copyright problems, privacy issues, advertising rules, music licenses…” “When I asked what he wanted to make videos about, he said, ‘I don’t know.’” “Hahaha. He’s already run out of ideas.” His wife smiled. “Maybe. But I still want to support him.” “Support him in becoming an influencer?” “Not necessarily. I want him to learn the skills behind it.” S...

And that evidence could not be measured by a DNA marker.… When Aya’s daughter was born, there was one fact in the delivery room that required no laboratory test. Aya was the person who had given birth. The question of the father was different. For centuries, people had tried to answer it indirectly. A newborn’s nose resembled the father’s. The baby’s eyes looked like the grandfather’s. Perhaps the parents shared a particular blood type, and the child had inherited a combination that seemed to fit. But resemblance is not proof, and blood groups are much better at excluding some biological relationships than confirming a particular father. Two unrelated men can have similar faces, and millions of people share the same common blood-group combinations. Aya’s husband, Ren, had never questioned that he was the father. Then, during a routine family discussion, someone casually mentioned genetic testing. The suggestion unsettled hi...

Then, when the camera starts rolling, be yourself.… The first time Lena was cast as a neurosurgeon, she panicked. She had built a modest following by appearing in low-budget online films, where directors liked her precisely because she did not seem to know the usual tricks of screen acting. She had never attended a conservatory. She had no famous parents, no Hollywood friends, and no instinct for the theatrical gestures that could make an ordinary line sound important. Her previous roles had been stranger. A nightclub worker in Detroit. A single mother who claimed to have been born on Venus. A delivery driver trapped overnight in a supermarket during an artificial-intelligence blackout. Now the script called for her to play Dr. Mara Voss, a world-famous neurosurgeon performing an awake craniotomy. She called her manager. “I’ve never operated on anybody,” Lena said. “How am I supposed to play a brilliant surgeon?” Her man...

“Trust me. I am me.”… At 8:17 on a Monday morning, Aya received a message from her bank. A transfer had been attempted from an account she had never seen. She opened her banking application. Her password still worked. Her phone was still in her hand. Nothing appeared to have been stolen. Yet somewhere on the internet, someone was behaving as Aya. The problem, she realized, was larger than a stolen password. For years, people had spoken about “identity verification” as though identity were a single fact that could be checked. Show a passport. Take a photograph. Compare a face. Enter a phone number. Answer a security question. But each method proved something different. A passport could establish that a document had been issued to a particular identity. A biometric check could establish that a living person was present. A cryptographic credential could establish possession of a particular secret. None of these, by itself, answer...
