One problem with modern digital storage is the lifespan of the storage medium. Compact discs only last about 10 years, and the "longer-term" magnetic tapes are not much better at about 20-30 years [1].

It seems like we've made the tradeoff towards increased convenience of access vs. reliability, not the other way around. Hopefully new tech is developed that reverses this at some point, without relying on higher-level systems built on top of unreliable media (e.g. Amazon Glacier, Archive.org, etc.)
