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.
They say “billions of years” but that sounds like just the sort of thing a stray cosmic ray would ruin.
Maybe they’re planning on using a checksum for error correction like they do with RAID.
On that timescale, what are the odds that the checksum is still reliable?
Why would it be any different from the real data? Checksumming is basically just writing extra copies with math.
I’m asking why it would be more reliable if it has the same vulnerability to being corrupted.
What would be the point? You would just know that the data is invalid. You couldn’t fix it
