What is particularly intriguing about the way in which the story "There Will Come Soft Rains" begins?

The opening paragraphs of Ray Bradbury's short story "There Will Come Soft Rains" are particularly intriguing in the way he portrays a silent, futuristic smart home without any family present. While Bradbury depicts the convenient voice clock and overhead speakers informing the residents of the time and their daily reminders, he also emphasizes the emptiness of the home.
As the technologically advanced kitchen stove prepares a full breakfast and the memory tapes play their routine messages, the absence of the family is particularly intriguing. The reader is immersed in the setting and the mystery surrounding the family's absence is rather disturbing and ominous. By illustrating the glaringly empty technologically advanced home, the reader is intrigued to learn where the residents have gone or what might have happened to them. It is only after the various mechanisms inside the house clean up breakfast and the sun begins to rise when the reader learns that it is the only home standing in the wake of a nuclear attack.
