As Einstein said in 1955, when the existential threat was both new and real, “You may reasonably expect a man to walk a tightrope safely for ten minutes; it would be unreasonable to do so without accident for two hundred years.”
We are complacent at our species’ peril. How many intelligent civilizations in the universe have ended shortly after the dawning of their nuclear age? That’s one possible explanation for the Fermi Paradox.
Thus far, humans have been unable to resist use of a technology to gain power and the abstention from use of nuclear power seems only as strong as the current world power structure, which will inevitably fail. There are no easy solutions to this problem but it’s one we must solve to survive. Perhaps we even need to change ourselves biologically, as a species. To engineer ourselves off the paleolithic savannah into one fit to survive in the modern world of nuclear powers and interconnection.
