"It'll be possible to guess fairly accurately whether you are single or in a relationship, how much money you make a year" Well, you could probably get a decent guess just by looking at the house and garage. Some things have always been easy to guess accurately, but one novel problem is that we need more and more effort to be anonymous, online and offline. Double lives may be desirable for some, and it's just getting harder. Now you can at least withdraw a wad of cash, leave all your cards and electronics at home and be reasonably anonymous. In the near future you would probably need face paint to avoid image recognition and even further on you would need to subject yourself to an electro-magnetic pulse to get rid of nano-robots you can't wash away.
