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.
It makes me think about how the 2.5d glass screen protectors with bevelled edge eventually became 3d for curved screen phones, then 5d, then 9d, and I’ve seen some silly 1000d and 9999d because clearly none of these marketing idiots remember what the d numbers even referred to in the first place. They used to explain what each d gave you and now its just a number and higher is better.
