I'm going to just read "limitation on Chrome" as "purposely defective by design" as there's sufficient incentive to delay disabling to let a few telemetric squeaks escape.
The scene mentioning the big EMP-reset in Blade Runner 2049 made me wonder just how much would be lost to us in such a scenario. Much that we care about is currently on highly sensitive storage.
What format should I invest in (developing/purchasing/etc) that would A) be easy-ish to read from B) be dense enough to exceed the point I might as well just be using paper/glass slides/microfiche/and so on, and could be ramped back up from pretty crude tech.
Combine "end of civilization", "time-travelling with tech", and other thought-experiment scenarios for fun.
This reminds me of a conversation I had with an archivist acquaintance I met at a conference. Her opinion was that I should donate my personally acrued private assemblage of retrocomputing game systems and personal computers to the Living Computer Museum, out of the belief that they'd be under better care there than in the hands of a private collector.
While LCM volunteers may have a keen interest in preservation, I don't feel there's the same sense of ownership as systems literally brought back to life/restored by the hand of the person who purchased them expressly for the purpose of sharing those experiences.
