Hello, people of the future! Please unfreeze us, and give us warm soup! We'll be very grateful! Thanks much.

Seriously, though, I wonder about the ability of future archeologists to dig through historical Internet information. At the moment, the only attempt to create a thorough historical archive of the Internet is the Wayback machine, and since (I estimate) that the growth of the Internet is accelerating faster than the cheapness of reliable long-term storage, they'll either have to get lots more funding or start being more selective about what they archive.

In terms of the ability to maintain information of interest to future archaeologists through a straight-up global disaster, the Internet isn't any better than paper. Maybe we need to start looking into cuneiform printers...
