This is a most excellent place for technology news and articles.
I remember reading abiut this possibly 10 years ago or more. It's insane how long it's been in development
0.1% of the intended storage duration?
Given the 20 years of development between the first VTR and VHS, the 100% development to storage lifetime of that technology seems pretty large in comparison.
Also, how silly would it be if we put things into glass for 10,000 years and then 5 years later there's a format war like VHS vs Beta and we need to redo everything?
Intelligent life in the future will find 10,000 year old records from present day humanity and be so frustrated by the multiple competing formats over the first 100 of those years that they won't even bother trying to read it.
Of all the things to take time with to get right, extremely long term storage seems like one of the more prudent.
