Digital information and toner/ink on paper will not last nearly that long.
Maybe humans of this age should be curating some etching on stone or even more durable materials, to record some of our history for posterity?

So, intermediary at best. My understanding is that R/W CDs are far less durable than earlier write-once CDs, but probably far less common for mass storage.
In the early 1990s I worked for a CD foundry. We mostly made CD backups of nuclear plant records, and short runs of off-brand music. The resist dye got EVERYWHERE, because humans spill things; red blotches on everyone's work shoes.
If those "3 year" predictions meant anything, half of our business would have gone for tape backups.... Don't know if it's accurate, of course.
And for predicting things, it's been a decade since I bought a computer with a disc reader of any sort.
I thought they'd last forever, decades anyhow, but I wonder now. What good are stone cds, if there are no readers in 50 years.
The CD foundry job must have had fun moments.
