“The point is, none of these electronic devices will stay in service long enough to make information available even ten years later.”
I have loads of archived readable data from over 30 years ago.
How about from 100 years ago? I have books that are relevant right now from the early 1900s, with no modern equivalent.
I also have some pretty cool stuff from the 1970s, but with no way to read the media.
Got anything on 1600 BPI nine-track reel to reel magnetic tape?
Thumb drives are based on FLASH memory. Those will hold their contents for twenty years. External hard drives appear to last about four years or up to its first drop.
The point I was making is that electronic media changes about as often as we change underwear. Printed books are the only true non-volatile memory at our disposal.
