Because this is the talk of the #internet again: you don't preserve digital media by stuffing the One True Version in an #archive. Make countless copies and scatter them to the wind. Make each a different format. You don't know which of them will still be readable next decade, so *don't try to guess*.
That goes for analog media too. The Library of Alexandria contained copies. Many classic paintings only survived as copies.
Copying is how life itself beats death. Embrace it.
