Agreed. But, we're missing the point quibbling about search histories and emails... That's nothing compared to what's coming. The data already exists to track your every move. It's just a matter of consolidating and organizing it. Right now, there is money to be made selling customer data for marketing and the like. This keeps the repositories of our data from sharing with one another. But, soon, the economics will flip. And, there will be money to be made from selling privacy. For instance, assume all credit card, phone, cable companies, etc. pool their data. For a monthly subscription, this conglomerate will keep your info (or parts of it) hidden. The default will be everything is knowable about everyone, except for those who pay a fee to erase info from their records. Far more money to be made selling privacy than selling info. 4th amendment and all the rest is moot. Our info is held by private international companies who, eventually, will begin charging you to keep things hidden from others.
