It's not the governments that will be your ruin. It's your curious neighbors, people you pissed off, corporations, marketers, social networks, criminals, crooks, malicious types, perverts, gossip spreaders, blackmailers, and identity thieves. Your privacy is gone, and it's not the government that's taking it.
I did not know that FBI and NSA all are thieves, criminals, crooks, perverts and blacmailers.
The average gangbanger and drug dealer are not trying to pass laws of backdoors and data retention. It is FBI CIA NSA and learned elders of zionism who are behind all this mass surveillance and nanny state.
If you're a normal person, then nothing you do is interesting. If the algorithms cough up something that it thought was interesting, then the people look at it. Then, again, if you're normal (i.e not some Boston bomber), then the person dismisses it.
Did that prevented Boston bombings? Did that stopped Breivik. No. And realistically it would not. And that is not even the true purpose of such surveillance. Total control and elimination of all dissent is what this surveillance is all about. With such total control no revolution or deviaton from official party ideology will be possible. Every single rebellion could be identified and crushed in early stages. Even before the rebels would start thinking about disobeying their supreme leaders.
Even though such control gives security, it still seems kind of frightening to me.
