Sophie Pinkham at The Nation:
Fedorov’s ambition was not limited to those still living. He imagined resurrecting every person who had ever lived. Inverting the idea of the duty of the living to future generations, he argued that we owe a “resurrectory debt” to our parents, and he insisted that as technology advanced, we would pay off this debt by piecing our families back together from bones and even specks of dust. (A crackpot visionary rather than a scientist, he was short on specifics about how we might do this.) To solve the problem of housing the vast resurrected population, he looked to space, proposing the colonization of the galaxy—a hope shared by people like Thiel and Elon Musk today. But Fedorov imagined the work and benefits of immortality as collective and universal. He accumulated a number of followers during his lifetime and after his death, and his reputation as an eccentric visionary endures in Russia.
