Here's why:
* Lack of Depth: The house is described as a marvel of technology, able to cater to every whim of the Hadley family. However, it lacks any internal motivations, desires, or emotional complexity. It simply functions based on its programming and the input it receives.
* Function Over Character: The house serves as a symbolic representation of the dangers of technology, the potential for it to become a substitute for genuine human connection and nurture. It acts as a tool for the children's desires, amplifying their destructive impulses.
* One-Dimensional Purpose: The house is consistently presented as a force of convenience and indulgence, ultimately leading to the family's downfall. Its role is to create an environment that isolates the family from the real world and feeds their desires, regardless of the consequences.
While the parents and children in the story are more complex, the house remains a flat, symbolic character driving the plot through its passive but powerful influence.
