Why on Earth would we lose the ability to read simple magnetic storage?
Yes, I can read data off floppy disk today due to having a floppy drive somewhere in my storage. And even if I didn't, it'd cost like at most 50 euros to get even a new reader. Get one off Amazon for 20 bucks.
And what data exactly are there on floppy disks that isn't on other media? Like... globally culturally significant data.
Can you read ancient Greek? I can't, but I still know about the Trojan Horse. I can't read Biblical Hebrew, but I know about the ten commandments. How?
