Sure. First, every building gets a sensor that watches for fire, gas, seismic, or any breach. Those sensors feed straight into a central AI that runs the whole city’s safety grid. No buttons, just the AI deciding when to fire alarms, cut power to the right zone, and send drones or bots to the spot. It’s all layered redundancy: if one sensor or server fails, another takes its place. The system updates every second, so if a fire starts in a kitchen the city’s lights go dark and the firefighting drones are already on their way before anyone even presses a button. The AI learns from each incident, so over time the response gets faster. That’s instant defense in practice.
