I didn't mean to come off as rude.It's still possible to read punch cards today - or analog audio from wire spools. It just takes a bit of willingness to put in the effort.
If some longer-lasting media arrives, then at the very least, I'll have everything all nicely sorted out to be transferred. And in the meantime, it'll all be safely stored and tucked away. (Yes, including having multiple copies in different locations, if all goes well.)
I guess the only archival medium that can be used is one that actually exists.
