The day held much promise as the Pizza Man and his cronies started about the factory. 'Twas the year 3025, the human race having long ago been annihilated. Artificial Intelligence roamed the earth -- robots of all shapes, sizes, and purposes. For the past hundred or so years not a drop of water had landed on the planet earth and all the lakes, streams, and oceans had frozen and lay stagnant, cloaked in darkness. It was the great Ice Age, but none of the beings on planet earth were effected. Pizza Man worked in a factory which created hover cars -- the latest and greatest -- and he was one of the richest robots in all of Europia.
As Pizza man walked outside to test the newest hover car that mysterious day in January, he felt a strange substance falling from the sky, and as he looked up to see where it had come from he saw a bright light and fell backwards to the ground, blinded. Hearing a crash, the other employees hobbled out to register what had happened. They, too, felt mysterious drops coming from above and they, too, looked up and were blinded. 'Twas the enigma that several centuries past was a commonality, but this new generation of robots were not created fro the new climate which had suddenly spread across the earth. Elsewhere in the world a miner's tunnel through the ice was suddenly filled with water. All the ice was melting. The whole world face a second destruction: the destruction of the robotic race. These new elements which previously had brought joy and growth to humanity now only brought calamity. All beings are created for survival in certain climates in which they live. If that climate changes too quickly, the beings are nearly instantaneously wiped out.
...one would wonder why "Pizza Man" was named after a food item when robots required no food for survival. But I suppose that's another story for another day...
