My take on it is privacy is dead or nearly and we have to have good legal protections of who can use what data and when. The privacy arms race will mostly be won by big government with lots of resources and enough willing/foolish patriots (Depending on your point of view).
It is just a shame that we have to go through the whole cycle given that we just know it should happen. But in a way, the more extensive the surveillance is, the quicker this cycle will happen. And right now we are in a pretty bad place already. So let's be optimistic!
