Should've included a bit more but the title does a good job:

  The Cameras Tracking You Are a Security Nightmare

The model is not entirely unhelpful: selling better drugs might be one of the few practical solutions here. If cameras have undeniably visible benefits for private companies and public safety (I think they ultimately will), then the question is how to build them in a way that avoids accrual of centralized power while providing the benefits. You can attack that problem from a lot of angles, but at the moment it is undeniably hard to build video sensing in a way that doesn't rely on centralized (computing) power.

Will public safety improve or will big brother have a stronger grip on your digital life?
