The original is badly damaged. Thankfully, we have this copy, and now that it's been recorded electronically in theory we will at least have this version forever. But in practice, I fear that a lot of data will disappear. Modern hard drives and ssds have a frighteningly short lifetime. There are some organizations that are trying to record some of this, such as the internet archive, but it is not clear to me that they are going to last in the long term.
I would like to be more confident that much of the works of the present and past (like this) will survive into the future.
