Curious that you mention tracks. Electronic communications leave tracks all over the place. But mechanical documents just have one finger print at a time. As chance would have it the Euro news this week has a story about the Russians placing large orders for mechanical typewriters. They say they are tired of their confidential info bouncing around the ether and are going back to hard copy documents for the important stuff. And I tend to believe that everyone in this country who has really really important stuff to get done doesn’t let it transmit to the web. Computer aided design/manufacturing/production does not have to be tied to the web. I have a machine room that proves that. My stuff is absolutely uncorruptible by an idiot in a Russian airport.
If you have your own uninterrruptable power system (generator), with pure 'sine wave'for 60 Hz , I might agree with you !
However , most people are dependant on public utilities, which permit possible communications (ie: Smart meters).
My own opinion is that Snowden has much more information to spill , and chances are it will be shocking to the American citizenry,
and I look forward to it's release.
I am not sure what is secure , and what is not !
