"There Will Come Soft Rains" explores the theme of Nature vs. Technology by depicting a world where technology continues to function despite the absence of humans. The story illustrates the ultimate triumph of nature over human innovation, emphasizing the transient nature of human actions and the enduring force of nature. Through the portrayal of an automated house and the natural world, Bradbury highlights the separation between humans and machines, and the indifference of nature to human existence.

The automated house, central to the story, represents human reliance on technology. It continues its tasks, such as preparing meals and cleaning, even though its human inhabitants are long gone. This symbolizes the dangers of over-reliance on technology, as the house is unable to adapt to unforeseen circumstances without human intervention. The house's inability to stop the fire that ultimately destroys it underscores the limitations of technology when faced with the unpredictable forces of nature.

Bradbury uses vivid imagery to emphasize the contrast between technology and nature. The "green snakes" of fire-fighting chemicals are depicted as battling the "angry" fire, illustrating the struggle between the house's defenses and the natural force of the fire. The fire, described as a powerful and destructive force, ultimately prevails, symbolizing nature's dominance over human attempts at control. This imagery highlights the futility of relying solely on technology to combat the forces of nature.

The house gave ground as the fire in ten billion angry sparks moved with flaming ease from room to room and then up the stairs.
[...]
From attic trapdoors, blind robot faces peered down with faucet mouths gushing green chemical.
The fire backed off, as even an elephant must at the sight of a dead snake. Now there were twenty snakes whipping over the floor, killing the fire with a clear cold venom of green froth.

The poem within the story further emphasizes the theme of nature's indifference to human actions. It suggests that nature will continue its course regardless of human conflicts or existence. Elements like "frogs in pools" and "soft rains" remain unaffected by human endeavors, including war. This underscores the transient and insignificant nature of human actions compared to the enduring and transcendent force of nature.

The tone of the automated house is neutral and monotonous, highlighting the separation between humans and machines. The house continues its routine without understanding the tragedy of its missing inhabitants, emphasizing technology's inability to connect with the human condition. This detachment further illustrates the theme of Nature vs. Technology, as the house's mechanical actions contrast with the natural world's indifference and resilience.
