Can you imagine how much work genealogy probably won't be in 100 years for our future descendants.  As a matter of fact I often think about how they may know too much about us. 

Thank you technology.  From cell phone records, to employment records, school records, credit histories,  driving records, computer records , Ipods, bank accounts, charge cards, our purchasing/shopping records, etc.

Virtually everything we do, we "sign up" for or there is something to track it.  I can just imagine what our future genealogists are going to know about us.  Our every move is noted nowadays.  In 100 years, will genealogy still be as much fun as it is now?
