I still have letters from 30 years ago. I would count that as being durable. I also deleted a lot of letters and journals by throwing them away. I was bitten by a platform that stopped existing and took content with it. I had not backed up my texts. I think what I am trying to say is that it depends. If it is important one secures it. If it isn't one carries the risk of loosing it. It doesn't necessarily depend on the medium. But I agree. Except from entries in one's journal 1on1s are really ephemeral in the real world.
