In computer security, every time machines become fast enough to breach the limits of an algorithm we invent something new so that “hard” problems remain “hard” and therefore encryption is still secure.

There has been no corresponding increase in the difficulty of invading privacy. 30 years ago, even though you probably “could” observe somebody for a long time and eventually connect some dots about them, it would not really have been worth your while (and you certainly wouldn’t have been able to do it for thousands or millions of people). Now, it is ridiculously easy for computers to dredge up information and instantly transmit it, slog through it and basically connect every imaginable dot. There needs to be a new standard for privacy: just like you want a 2048-bit key, you want the equivalent of a “make life a pain in the ass for Facebook” key on EVERY DETAIL of your life.
