But this has not happened. We have not been overrun by time travelers from the future. How can this be? It seems to me that this is because the necessary technology has not been developed, not because it could not be developed but because there was not enough time for it to evolve for the first time. The resolution to this paradox is fairly simple. Society has somewhere along this timeline stopped its inevitable technological march forward. The only thing that would cause this is the destruction of society itself. Whether from external or internal forces the whole thing collapses.
