How do you know it won't?
Just because some beliefs that used to be "wrong" are now considered "right", does not mean all beliefs that used to be "wrong" will in the future be considered "right".
As the quote says, "They laughed at Columbus, they laughed at Fulton, they laughed at the Wright brothers. But they also laughed at Bozo the Clown."
Maybe a better comparison would be mutually assured destruction. Enormous, world-level resources spent towards trying to ensure an outcome for something that no one wants to have happen. Those enriched along the way were the purveyors, not the population.
This is a bit of a tangent, but I think often of how wrong it is that we allow indoor marijuana production in places like Canada and the Western USA where it's legal. What a horrible waste of energy.
