People have always looked to the horizon and feared that which they did not understand. Initially, this horizon was the edge of the forest. Then, when forests became better explored and their dangers were realized as not actually being that serious, human attention turned toward the darkness of the sea. Then the sea became better explored, and the new horizon became the vastness of space. And now, with space getting ever better explored, a new horizon appears. . . in the form of the horrors humanity is about to unleash on itself.
