Daniel Kaplan questions the future of privacy in the age of the internet:

Protecting their privacy has value for individuals.

As well as my past bank card transactions, search engine queries, or detailed lists of all my local supermarket purchases? Not just to control what others do with this information, but to actually use it myself, to my own ends?
