The question here is not the future viability of nuclear power as a prime source of energy, but rather the continuity of a sane and stable world that will be able to be a good shepherd for this genie in a jar. Many informed sources hold that nuclear power (in it’s current iteration) is a ticking radiological killer that sees man’s understanding of the nuclear timeline as folly. Folly carried to the nth degree.
To put this another way: If a given amount of Plutonium was stored in Tutankhamen’s tomb, it would have the same properties today as the day the ancient Egyptians sealed the great pyramid of Giza.
Civilizations come and go (a fact). Radionuclides persist for eons (a fact). Putting it another way, does anyone really believe that mankind, given its propensity to do harm to his fellow man by any means possible, is a trustworthy and reliable steward for this awesome power?
Many say this is a fool’s errand.
