Actually, archivists and technologists have been working together to solve the problems of digital preservation for a long time. There is an ISO Standards for digital preservation systems - ISO 14721:2012 originally authored by and still maintained by The Consultative Committee for Space Data Systems (CCSDS, which part of NASA). There are commercial systems that were developed to these standards, among them Preservica (http://preservica.com/) which is used in many archives in Europe.

Archivists are acutely aware of the obsolescence of digital formats and media. And the solution cannot be just printing them out on vellum or archival paper because increasingly records are being created digitally that cannot be meaningfully or adequately converted into printed formats. I am talking about records that are audio, video, high resolution photographs (like those that NASA is seeking to preserve digitally) etc. Even emails when printed out onto paper would be missing a lot contextual information that would have been kept if you preserved it as a digital format like EML or MSG.

So, existing digital preservation systems may still be imperfect, but nevertheless we still need find improved solutions for preserving them digitally.

I don't work for CCSDS or Preservica. I work for a national archive as a specialist on digital records and archives, but my background is in IT having spent about 15 years in software development.
