Power of big data has been clear for a long time but for some reason nobody seemed to care. As if everybody didn't realise that their data, while they can be used for "good" purposes (precise targeting of advertising), they can also be used for evil to serve others' interests. For example to help somebody to power, though it remains to be seen if this really works. But what if insurance companies refuse to give me health coverage because my data is correlated to a pattern of people who have costly conditions?
