@Max The information it stores is still retrievable after 4,200 years
That will never happen with an iPad. The battery has gotten so low twice in the last week that the iPad wouldn't turn on. Fortunately, I had access to a $453,000 oscilloscope to charge it as did the phone next to the iPad (not mine).
The US National Archives decided long ago, that any medium preserved also requires the player of that medium be preserved too. Both paper and film need care to preserve them for posterity, not to mention the space it occupies. A lot of film has deteriorated, just ask Turner Classics. If not the deterioration of the celluloid on film [which by the way, is highly flammable], dyes have faded; if it weren't for digitalization, remastering and colorization, such works could be lost forever.
The US National Archives recommends porting older formats into newer ones, ad infinitum to insure the playability or readability of old documents, whenever possible.
As a persoal example, I transferred digital formats of the past to some generic format still viewable on most any modern PCs: Ashton Tate Dbase or Visicalc to delimited ascii text, or WordPerfect or WordStar, to ascii text. A big problem exists with analog formats: VHS tapes, analog cassette tapes, etc., that output NTSC or RGB video, as HDTV and digital audio made such devices rapidly obsolete; their lower quality relative to HDTV or lossless audio for the most part means conversion has little chance of data loss.
