You create embryos, which are distinctly uniquely a human, then destroy the ones you don't want. It's eugenics, just at an earlier stage of human development.
Over a decade ago I was a summer intern on the same team as Noah. I was a pretty clueless college student with no real work experience on a team of real experienced rockstars. It was a long time ago, but I still remember how kind and helpful he was. I barely knew what a terminal was, but I remember him walking over to my desk or going over to his, and having him explain things so cheerfully and patiently. He was so genuinely thoughtful and kind. Folks like Noah help shape the careers of the next generation and can make tech a good place to work. Rest in peace.
