As for the digital age's temporary permenence I have watched many storage devices come and go. In the case of floppy discs, they are not readable with todays operating systems. My other big concern is the vulnerability of electronics to outside influences, and the dreaded aerial nuclear burst to wipe out all. If man doesn't ruin us there is always the threat of a huge solar flare, which we are well overdue for. The last big one in 1859 took the telegraph offices down, some catching on fire and just imagine what it would do today. While this will temporarily put us in the 1800s, we can recover from this, just not the files. To this end I am going to get a dentist's lead apron to cover my computer and back up files.
