When I was 16, I was 'paranoid' about computer security. I used gpg, would never dream of giving my real name to any website. I distrusted every website.
Now I'm 31, and you can easily find 5 years of reddit comment history linked to my almost unique real name. Facebook has algorithms that can link my face to my real identity. I carry a location tracking device and microphone in my pocket. I sit in front of a camera all day. Google has all my search history. My ISP knows which sites I visit.
It's just incredible how comfortable I became with sharing this data about myself online. I don't know how it happened. My 16 year old self imagined that I'd have had some awesome technological setup that made me immune to tracking. But the truth is I just got used to the possibility of being tracked, and then forgot about it altogether.
But these NSA revelations have woken me up and I'm now back in that paranoid state and actively seeking ways of protecting myself.
I think many people have had the same experience.
For all the talk about the generations of the future being tracked and recorded from birth, I have to wonder if we're the dinosaurs and our kids will be saying:
"Shit Dad, why did you share all this stuff about yourself, are you stupid or something?"
