Interesting technology.
But if you want to preserve human knowledge in case of a collapse of civilisation, shouldn't you preserve it on something that doesn't need the highest technology of said civilisation just to access it?
Short version: In case of Doomsday, bring a book, not a PDF.
Best preservation method for important information has always been to spread it though.
The 5D part in the description is kinda debatable anyhow. Size and orientation are subsets of a 3 dimensonal space. Not additional dimensions.
But hey, it makes it sound more Sci-Fi.
So I'm not blaming them.
Jokes aside, that whole project at the University of Southhampton is part of a project to store genomes of all kinds of creatures, plants and even bacteria in a digital and non-perishing form for future generations. Or even alien visitors.
The hope is that what is extinct could be recreated by someone with the proper future technology.
That's probably why they hide those disks in a salt cave in australia.
It's the obvious place to look for signs of a vanished civilisation...
The whole spirit of that project urges me to quote a famos american author:
"That is not dead that can eternal lie.
Until, strange eons, even death may die."
Future inhabitants of this plane of existence will refer to us as the Great Old Ones I'm sure.
And if they have half a brain they let us R.I.P
PS: That technology is slow as f**k and expensive too. Not exactly the backup media of tomorrow. Also no re-writing. What's etched stays etched. But yes, for all intended purposes it lasts forever. So purely as an archive it does a tremendos job.
