Stroll through a few blocks of midtown Manhattan and you'll end up on hundreds of security cameras and in the backgrounds of a handful of tourists photos. Add a few more years and your image and gait will be continuously recorded by a swarm of 3D camera phones, self driving vehicles, and police drones. Authentication of a crime may require not one but a diverse set of recordings from multiple entities. Validating that the person you are talking to on Skype is indeed your mom may require a cryptographic key exchange (and a damn good reason it won't be Skype but a tool that can be verified by third parties.)

For those of us who grew up reading Neuromancer, Snow Crash, and other cyberpunk yarns: that is today, we are living in that world at this moment.
