Random thought - Future Historians?

As I mentioned earlier, I'm currently reading David McCullough's "John Adams". So this morning, I was riding the bus into work, and listening to the book on my ipod.

In the book, John Adams is currently stationed in Paris, tasked with finding a peace settlement that will be acceptable to both the English and French. He's also stressing because his daughter might marry somebody of ill moral character....so he decides to write her a letter.

The author mentions that the letter never reached Nabby (his daughter - terrible name), so how did we come to learn of the existence of the letter? Were the founding fathers so vain that they used carbon copies when writing letters?

Note - when I talk of carbon copies, I'm not talking about CC's on emails....I'm talking about real old school carbon copies, and putting things in triplicate.

That brings me to my next random thought. Imagine that I eventually grow up, and end up doing something amazing with my life. Something noteworthy. Something that causes best-selling historians to think "this guy is worth writing about".

Will future historians have access to google's servers for my email trails? Will they access my employers sametime servers? I mean, who writes letters these days? Will our electronic trail be used to piece together our stories by future historians?
