I think seamless persistent storage is also bound to fail. There are significant differences on how we treat ephemeral objects in programs and persistent storage. Ephemeral objects are low value, if something goes wrong we can just restart and recover from storage. Persistent storage is often high value, we make significant effort to guarantee its consistency and durability even in the presence of crashes.
“Persistent memory leaks” will be an interesting new failure mode.
Anyone using object storage at scale (e.g. S3 or GCS) is already likely to be familiar with this.
