Let's put it another way. It's not really the death of privacy. It's the appreciation of personal information. A long time ago you could, if you had the means to, get an individual's life totally mapped out and that had some value. But today you can map an individual's life and then connect the dots between that individual's personal data and that of the people they interact with and build a social graph. And that is infinitely more valuable. Now that Google and Facebook can earn up to $50 per head, they are really motivated to eradicate online privacy. If you wanted to and if you could afford it, you could maintain your privacy. It would just cost exponential more than it would have cost just a few decades ago.
