Yeah, I think as long as we can count on some level of society, we have a shot at longer term preservation. Like, computers will continue to get faster, and mediums will continue to get upgraded and transferred and so forth, and we're kind of already at a point where nothing recorded today needs to be "lost" with some careful planning. There are obvious holes in this, but it's increasingly less likely to be a problem that the storage medium is the issue (again, caveating that we're not talking about rebuilding society after a catastrophe or something) and more a problem with what the dependency of reading the data to be saved is, whether it's transferred on storage formats that maintain data integrity, etc.

Like, we can do redundant backups and so forth, but what if the things we're backing up are server dependent? Or even simpler shit like Flash games. I really hope that more people writing software especially think about how to keep it usable for a long time.
