Privacy
Some days ago 35mio US veterans got their identity leaked by some government arm. And when I use some new webservices they have an IMPORT FUNCTION - to import all addresses from YahooMail, Gmail... I can see this ID Theft going ballistic the next coming years.. DAMN It stupid.
So when I turn 65 my grandchildren will ask me: "So Granny how was life back then with Secure Identity and no obesity ?".
