Why was the house the protagonist in there will come soft rain?

In Ray Bradbury's short story "There Will Come Soft Rains," the house serves as a protagonist to illustrate the theme of nature versus technology. It operates autonomously, performing daily tasks despite the absence of its human inhabitants, who have perished in a nuclear disaster. The house symbolizes the relentless march of technology and its inability to replace human life and connection, ultimately highlighting the futility of human endeavors in the face of nature's indifference. As the story concludes with the house's destruction, it underscores the idea that technology cannot escape its own vulnerabilities.
