The document discusses how the world is becoming increasingly "programmable" through networked technologies and sensors. It notes how physical infrastructure like roads and parking meters can be enhanced with digital interfaces. The concept of "cultural software" is introduced, where digital culture is encoded into everyday objects and environments. Examples of programmable elements are given like traffic lights and parking meters that can collect data and respond to their environments. The talk argues that as more physical things become networked and sensor-enabled, they will form new types of relationships and conversations between people, software, and the built world.
