From my perspective, they are all one in the same. The Nature of the Future by Marina Gorbis goes into this. We will use surveillance on ourselves (i.e. Big Data) to help the collective self-govern. An example in the book was people putting micro tracking devices on their water taps to monitor water quality levels, so awareness is immediate if the water quality drops.
I mean don't get me wrong, again I think we should be able to control what we choose to share, rather than it being take from us without our permission. But that said though, we say we're concerned about our privacy, yet I see more people speaking openly and very loudly on their cell phones around me, relaying their entire personal lives to the world. I even heard someone sharing their credit card number over their cell phone the other day. It's just idiotic.
The future will be sharing more openly and publicly to help each other out, rather than to help just a select few (i.e. businesses & governments). That's because in sharing this information, we will empower all ourselves collectively with this shared knowledge. So it's not about a few creating economic power but the many creating social power.
Again though, this is why we need open Web platforms to do this, so you can control your information and thus your identity in turn, similar to what Doc Searls is getting at within his book.
