aah yeah its already happening.. think abt it. how many people got your address?? how many people already have your mobile no. ? how many know your bank account number, or which bank u deposit money in..
technology will definately help mankind become even a more powerful species but all this would be at the expense of a few people knowing everything abt everyone..
it's only a matter of itme that this would happen... you cant avoid it..

its always been like this.. a mighty few controlling the weak masses, just that now it would be different but the ideology remains the same.
