The march of technology destroys as much as it creates, which would be okay if the things it destroyed were bad things, but they aren't.
Old recordings were digitized when digital audio first appeared. The early digital transfers sounded awful, of course, because the early digital technology was crude. Since many of the original recordings were thrown out after the copies were made, all we have remaining now are poor-quality copies.
Same with video and documents. If you need a schematic drawing of some circuit or a mechanical drawing of some physical assembly, you will likely be presented with an unreadable low-resolution scan or worse, a fax, or worse, a scan of a fax or a fax of a scan. When this happens, the information in the original document, the original design, is gone. The information that you needed was in the detail. Unfortunately, the part numbers, the component values, the dimensions, and all of that information in the document is in a finer scale than the crude resolutions of the storage and transmission media. Consequently, all of that information is gone.
They scanned the original and threw the original away. And, nobody can read what replaced it.
