I’ve often wondered what the implications of the internet will be for future historians. On the one hand, there is now an enormous body of writings from not just the educated elite as in the past but from all sorts of ordinary people, which is something that has never really existed before.
On the other hand, how and for how long will these writings be retained? If we stop writing things on paper, will these digital writings become completely inaccessible at some point? Could we have a situation where there are almost no writings from a certain period down the road? That would be unfortunate.
Freely licensed works will be preserved a lot better because there will be more copies of them.
Likewise the fediverse is a step in that direction: this message will be federated to hundreds of servers so is more likely to survive longer than if I posted it to reddit.
Already a lot of stuff is becoming one harddrive failure away from being lost forever. Companies don't care about preserving content, so it's largely up to random people happening to have saved a copy of something for it to still exist at all.
There are so many way to adequately protect digital information from solar flares. That would be the least of our problems, the actually dangerous part of geomagnetic storms is the severe power outages and the severance of the electrical grid.
