Don’t mistake map programs’ inaccuracy for your phone’s GPS. Map programs are often confused by network resolution and switch server locations with your location. Don’t assume someone with ill intent will do the same. Smart phones are a surveillance state’s wet dream.
I know more about the back end than the front end of IT.
Most databases of corporations, of credit bureaus, of government have a high rate of erroneous data.
The errors range from harmless to comical to very harmful. The bad quality of data harms more people, and more severely than intentional surveillance does.
Our society, like the mayor of London, has a tendency to redefine things as just “life in the big city”, or “the cost of doing business”.
But most of us are very illogical in which costs and harm we accept and which outrage us.
