How does one archive data for long term storage in 2020? From what little I've read, all of the media accessable to the layman has an archive lifetime of less than 30 years before physical degradation- NAND, tape, disc, whatever. That makes for a brittle civilization when the vast majority of our knowledge is stored on media and would be unrecoverable just 3 decades after a global calamity.
