In Jonathan Safran Foer's "Extremely Loud and Incredibly Close," the narrative explores intriguing ideas about technology and its potential to influence human behavior and urban design. One proposition involves guns equipped with sensors in their handles that could assess a user's emotional state, preventing the weapon from firing if the person is angry, regardless of their role, such as being a police officer. This raises questions about the intersection of technology, emotional intelligence, and public safety.

Additionally, the author imagines skyscrapers with adaptive features that could change their structure, allowing for flexibility in design and functionality. These buildings could rearrange themselves to accommodate various needs, such as opening pathways for aircraft to navigate through them. This creative vision of urban architecture reflects a desire for innovation that enhances safety and efficiency while transforming the urban landscape.
