Explanation:

"There comes a soft rain" was written by Ray Bradbury, during the cold war, when the whole world feared that a nuclear war would ensue. The short story presents a narrative where all the humanity of a city was decimated by an atomic bomb and only one house was able to stand after the explosion. This house is highly technological and autonomous and does not realize that it is no longer inhabited by people, for this reason, it continues to perform its tasks normally, until a fire starts inside the house. Despite closing the doors and summoning the robotic mice to end the fire, the fire takes on uncontrollable proportions and ends up destroying the house completely.
