Jeffrey Epstein's international trafficking agents send him pictures and descriptions of blue-eyed young girls: potential victims. One of Epstein's victims wrote of being chosen for her eye color in a journal entry later shared with federal prosecutors. "Superior gene pool?!? Why me?" she wrote, describing Epstein's worldview as "Nazi like." "Why my hair color and eye color?" Epstein himself blue-eyed " seemed to prefer both his victims, and the people he bankrolled, to have blue eyes. "All of my fundees have blue eyes," he boasted in one email. In the entryway of his Manhattan townhouse, he displayed dozens of prosthetic eyeballs in a frame. Going deeper into the files, Epstein and his network of contacts discussed beliefs about how physical characteristics and race might denote intelligence. They exchanged emails about population control. They spoke of engineering women's sex drives, building designer babies, and living in a world full of superintelligent humans that could merge with robots. The files offer a glimpse into a world where ideas about eugenics and race science have never gone away. On the contrary, they run through our elite universities, through the most powerful companies in Silicon Valley, and through the tech industry itself. Epstein's was an exclusive club that [dreamed] of re-engineering human minds and bodies, seizing control of our collective future, and building technology that, they hope, will one day merge with ... all of us.
