While this has been in my consciousness, I can't say I ever thought too seriously about it. Until yesterday, when I was lounging on a lawn in the park. I watched a woman take a photo, of which I was most likely in the background. The photo will likely be posted online, along with date and possibly GPS information encoded. Though I'm in the background, likely blurred, I can fully visualize a system that would combine near-certain images (a security camera is 90% positive it saw me three blocks west of the park at 2pm), with the blurred image taken at 3pm in the park, 30% likely it's me, with another security image taken at 4pm 2 blocks east of the park with 85% certainty. In other words, 10 years from now these algorithms won't just be able to follow my every move - they'll be able to go back and scan all the pictures uploaded, ever. And compile a film showing every waking hour of my life. A timeline, really.
