This is important and should be a top-level post. I think many people miss this in discussions about privacy, and this is the reason I believe the privacy is dead. Everything you do is metadata about everything else you do, about everything else people around you do. You can infer any piece of "data" you want given enough (meta)data sources and computing power.

Thus the only way we can keep privacy would be to roll back the last 50 years of technological progress, and that's why I'm starting to entertain a thought that we (as a society) should drop the concept entirely and tackle the change head-on, instead of being dragged there by force by the ongoing progress of technology.
