Resumen
There is an imminent expansion of cyberspace into physical space in the form of networked cameras, biometric identification devices, radio-frequency identification (RFID) tags on consumer goods, and a wide variety of sensors. The electronic networking of physical space promises wide ranging advances in science, medicine, delivery of services, environmental monitoring and remediation, industrial production, and health monitoring of people and machines. It can also lead to new forms of social interaction, as suggested by the popularity of instant text messaging. RFID tags are a nearer-term means of binding diverse information collected by sensors and cameras to individual items, since each tag has a unique identifier. When sensors, cameras, and tags are pervasively embedded in the environment and networked, anyone in the world willing to pay a fee (exponentially decreasing over time) will be able to get information on anyone else. Social and political conformity is a plausible result.
