"In my city we spent $1.6 billion on a new ticketing system for the trains. We replaced paper tickets with smartcards and now they can tell where people get on and off. So, question: how is that worth $1.6 billion? People say it's the government being incompetent, and ok. But this is happening all over. All the transit networks are getting smartcards, the grocery stores are taking your name, the airports are getting face recognition cameras. Those cameras, they don't work when people try to avoid them. Like, they can be fooled by glasses. We KNOW they're ineffective as anti-terrorism devices, but we still keep installing them. All of this stuff--the smartcards, the ID systems, the "anti-congestion" car-tracking tech--all of it is terrible at what it's officially supposed to do. It's only good for tracking the rest of us, the 99.9% who just use the smartcard or whatever and let ourselves be tracked because it's easier. I'm not a privacy nut, and I don't care that much if these organizations want to know where I go and what I buy. But what bothers me is how HARD they're all working for that data, how much money they're spending, and how they never admit that's what they want. It means that information must be really valuable for some reason, and I just wonder to who and why."
