, there will be challenges, no doubt. As you said, it is unstoppable. Slightly easing my mind is the general principle that the more data that is available, the less broadly that the data is used. Perhaps near-future capabilities would allow
us to see the name of every stranger in a public place, but would we want to
? It becomes an issue of information overload, promoting greater selectivity. Through Facebook, we can easily learn a lot of very personal information about co-workers or strangers that live near us, but when there is so much of it available, it becomes less and less relevant.
A small amount of personal information becoming public leads to feelings of exposure and real dangers. But in a sense, a huge amount of everyone's personal information becoming public actually restores privacy. It's the principle of being "anonymous in a large enough crowd".
To give an absurd and uncomfortable example that drives home the point, imagine the outcry if a few public bathrooms had cameras installed that were constantly live-streaming to the internet, with all historical footage available. How different is it if everyone's POV is constantly recorded and available to everyone else, such that 30 billion "bathroom moments" are uploaded to the internet per day? Strangely, that becomes less invasive because it is so commonplace that it isn't very interesting, and the privacy violations are "lost in the crowd".
It's an interesting paradox.
