Predicting has a spotty record in science fiction. I've had some failures. On the other hand I also predicted the fall of the Berlin Wall and the rise of fundamentalist Islam... and I'm not happy to be right in all of those cases.
It is good to express a thing twice right at the outset and so to give it a right foot and also a left one. Truth can surely stand on one leg but with two it will be able to walk and get around.
