Let me know when the nuclear war is going to be so that I can get it on my Outlook calendar.
That digital is somehow not "archival" because it requires electricity is a casuistic argument that ignores what you have to do to make most film viewable. Film requires electricity to convert into any usable format, unless you like solar powered viewers and slide film. The event that magically destroys the cloud and all locally stored copies of digital files will also likely wipe out the power grid, running water, and everything else that would affect viewing things on screen or allow them to be printed with an optical enlarger. As to individual carelessness, it happens with analogue materials too. People pitch printed photos and lose/destroy/dispose of negatives all the time. And there is generational rot where I get, for example, my grandparents' blurry and poorly exposed travel slides, scan all of them, and then don't have any place to put 200 Bell & Howell slide cubes.
I have TIFFs from 22+ years ago that are still readable. But I am more worried about the following, all of which have been happening in that timeframe:
- That maintenance support for film cameras is no longer convenient, fast, or cheap
- That the last good enlargers were made several years ago now.
- That few really good film scanners are still being made at a price point that is even remotely affordable.
- That environmental concerns are driving up the cost of the silver process.
- That the creeping war on incandescent lighting will eliminate the halogen bulbs needed for multicontrast printing.
The only thing that is actually safe is dark-stored, printed copies. That's the miracle that saves things, and you can get that from any source, digital or film.
