I think you'd agree it's quite possible to take high-quality footage and record every frame of it using current technology. What, a few terabytes maybe? Now, single an individual out. Now, data-mine those terabytes of footage. Even without exotic facial recognition or incredible resolutions, you can trace the exact movements of an individual, and of every other person whom they contact. It's not just a question of resolution. It's a question of software and big data, which is very different. And it's a question the ACLU would be very interested in. Don't throw out the critical concerns of privacy just because you can nitpick a few holes in the writer's technical understanding. It's bad form, and deliberately misses a valid point. A credible source focused on privacy is concerned enough to write about it. Dismissing it out of hand because the author isn't as much of a nerd as you is not a good argument.
