One thing this shows is just how powerful Facebook could become/already is. When they connect the dots online and offline of billion user's buying information and habits they essentially can electronically understand who you are better than you do, and can predict what you'll do even better. Just food for thought.
When Facebook connects the dots online and offline of billion users' buying information and habits, they essentially can electronically understand who you are better than you do, and can predict what you'll do even better. Why are people disturbed by this?
Simply put, because the corner stones of democratic societies are built on the assumption that peoples lives are private.
Take voting without privacy. Can voting work if everyone is fully known by the state? If the people in office known where the oppositions voters are, new actions become available. If you can redirect road work, sporting events, sales, and so on, how much work would it really be to get the oppositions voters to spend the day doing something other then voting on the election day? Knowing who votes for who allows those already in power an unfair and destructive advantage over those not yet elected.
Take politics in general if we have no privacy. What happens to politics if every to-be political rival is known to those threatened? If we can identify which kids are going to be political active, those could be discourage. Alternative, they could be influenced, drag into the party line before reaching a independent view.
Or lets leave politics and go to justice. Can you have a working judge and jury system if everything about their life can be fully known? If one party know that a jury members spouse is cheating, they can rephrase their statements in form of betraying. If someone know about economical troubles, one can redress statements as being "down on the luck". If the judge dreams about leaving the bench and begin some childhood dream project, one could phrase statements in favor of startups. Knowing the dreams and thoughts of people, and you get boundless possibilities to influence others.
