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.
Nice. We need something like this. Digital archiving is still best done on magnetic tape as disk and flash drives all fail after a few decades. But even for regular users, it’d be nice to keep a digital copy of family photos that lasts forever.
