The entire information world is either a database or a cache (or communication between them), layered on top of each other over and over. Every new storage technology typically ends up being yet another layer as either database or cache (or both). This case is pretty unique in that it can actually serve to remove a layer: ram (typically a cache) is not necessary if nvs is viable at the same speeds. But in general new storage tech just adds another layer, which the software world reacts to by rushing in as if to fill a void by creating new software to take advantage of it which ends up being... another database or cache, often with similar tradeoffs to the layers of cache/database surrounding it. In the limit, I see more and more layers of cache/database until they merge into some kind of continuous data/cache field with a continuous tradeoff gradient between size and latency.
