So much of what we know about the past, especially about ordinary people, is because someone came across old letters or diaries. How does that happen when everything is on old or obsolete devices that no-one's looking at?
I recently came across a carrier bag of photos from late DH's military service in the 1990s. Very interesting, but they'd have been lost forever if they were on a phone or PC I didn't know about or couldn't access.
How will future generations learn the history of ordinary people? I know there'll be official records of the big stuff, but what about the rest?
