This, then, is not a biography of Other Naomi, nor does it offer a psychoanalytic diagnosis of her behaviors. It is an attempt to use my own doppelganger experience—the havoc wreaked and the lessons learned about me, her, and us—as a guide into and through what I have come to understand as our doppelganger culture. A culture crowded with various forms of doubling, in which all of us who maintain a persona or avatar online create our own doppelgangers—virtual versions of ourselves that represent us to others. A culture in which many of us have come to think of ourselves as personal brands, forging a partitioned identity that is both us and not us, a doppelganger we perform ceaselessly in the digital ether as the price of admission in a rapacious attention economy. And all the while, tech companies use these data troves to train machines to create artificial simulations of human intelligence and human functions, lifelike doubles that carry their own agendas, their own logics, and their own threats. What, I have kept asking myself, is all of this duplication doing to us? How is it steering what we pay attention to and—more critically—what we neglect?

SEED: The doppelganger-culture framing could anchor an essay on how personal branding partitions identity and shapes what we attend to and neglect online.
