A.M. Gittlitz in the NYT:
Gorky was a fan of the Cosmism of Nikolai Fyodorov and Konstantin Tsiolkovsky, a scientific and mystical philosophy proposing space exploration and human immortality. When Lenin died four years after meeting with Wells, the futurist poet Vladimir Mayakovsky’s line “Lenin Lived, Lenin Lives, Lenin Will Live Forever!” became not only a state slogan, but also a scientific goal. These Biocosmist-Immortalists, as they were known, believed that socialist scientists, freed from the constraints of the capitalist profit motive, would discover how to abolish death and bring back their comrades. Lenin’s corpse remains preserved for the occasion.
Bogdanov died in the course of his blood-sharing experiments, and other futurist dreams were sidelined by the industrial and militarist priorities that led up to World War II. In the postwar period, however, scientists inspired by Cosmism launched Sputnik. The satellite’s faint blinking in the night sky signaled an era of immense human potential to escape all limitations natural and political, with the equal probability of destroying everything in a matter of hours.
Feeding on this tension, science fiction and futurism entered their “golden age” by the 1950s and ’60s, both predicting the bright future that would replace the Cold War. Technological advances would automate society; the necessity of work would fade away. Industrial wealth would be distributed as a universal basic income, and an age of leisure and vitality would follow. Humans would continue to voyage into space, creating off-Earth colonies and perhaps making new, extraterrestrial friends in the process. In a rare 1966 collaboration across the Iron Curtain, the astronomer Carl Sagan co-wrote “Intelligent Life in the Universe” with Iosif Shklovosky. This work of astrobiological optimism proposed that humans attempt to contact their galactic neighbors.
