Researchers at the University of Southampton in the UK successfully stored the entirety of the human genome sequence onto an indestructible 5D optical memory crystal no bigger than a penny. The indestructibility claims are no joke since the discs can withstand temperatures up to 1,000°C, cosmic radiation, and even direct impact forces of 10 tons per cm2.
Digitize all national history, literature, and culture. Put them on a hundred of these and distribute them all over the world. Refresh every 6 mos. Keep one on a server that all the kids can access.
Next time there’s war or whatever intolerant culture comes into power, and loots the museums, stops culture, or blows up statues, at least you’ve kept the history alive.
Think of it as the Library of Alexandria in horcrux form.
P.S. Important to include a user’s guide, reference schematics for the reader, and FAQs, etched into something semi-permanent alongside all the copies.
If it’s anything like the similar optical data storage crystals, it’s write only.
They probably have no way to read these yet.
