i dearly hope that rich investor man and private collector of space and spaceflight ephemera steve jurvetson has an end-of-life/etc plan for his frankly absurd collection
you may have caught a glimpse of this collection when he invited curiousmarc to come pull the modules from his apollo guidance computer to retrieve yet more unarchived AGC software. Not just ANY AGC either, the one bolted into a fighter jet by NASA to develop digital fly-by-wire, still racked up with the entire setup that went into the plane.
or you may have seen a tour of this collection coming out on scott manley's channel
and my god, as much as I'm delighted to see that this much stuff exists, preserved, archived, and cared for in one place, I can't help but worry about what happens to a private collection when the private collector is out of the picture.
there was a post on here within the past weeks or months speaking to the "it's not lost media if it's in a private collection/"lost media" doesn't mean "exists but isn't publicly accessible" it means "isn't known to exist at all" and i'm also reminded of that
I would consider it media on the precipice of being lost unless it's dumped and archived, like unique arcade machines bit rotting in some rich asshole's collection.
