There's a growing concern that our digital data -- something we thought was going to last forever on floppy disks, Zip Drives, CDs, DVDs, flash drives, etc. -- will not be preserved if the technology that stores them cannot be preserved. Good luck finding an Iomega Zip Drive these days. 

So what's the solution? 

There are a few forward-thinking projects underway right now to help transition data from decade to decade, century to century. But it's hard to imagine that we have books and scrolls that have been preserved for millennia, but we can't read a 5.25-inch floppy disk from 1989.
