paper superior to digital technology for archiving

From "Digital Information Will Never Survive by Accident”:

"Beagrie: In the right conditions papyrus or paper can survive by accident or through benign neglect for centuries or in the case of the Dead Sea Scrolls for thousands of years. It takes hundreds of years for languages and handwriting to evolve to the point where only a few specialists can read them.
...
In contrast, digital information will never survive and remain accessible by accident: it requires ongoing active management. The information and the ability to read it can be lost in a few years. Storage media such as paper tape, floppy disks, CD-ROM, DVD evolve and fall out of use rapidly. Digital storage media have relatively short archival life-spans compared to other media. As the volumes, heterogeneity, and complexity of digital information grows this requirement for active management becomes more challenging and more critical to a wider range of organisations."

I already have a problem reading/opening some papers/files that I wrote during my undergrad studies using WordStar (or something similar) in a school computer lab.
