Modern technology is gifting society with many wonders, including democratization by giving more creative power to individuals. In some countries the Internet is not allowed to be used for democratization, but for authoritarian control. One particular area is facial recognition technology which is how social media networks like Facebook can automatically tag your pictures with your friends. That same technology can be aimed at a crowd, and used to implement real-time tracking of where folks walk throughout a city. Supposedly the benefit is catching wrong-doers, but in every movie about ubiquitous monitoring the government doesn't use the information for the benefit of all, but to squash freedom.
