"Persist all data" shouldn't be taken as a literal notion. It's better to think about decisions of persistence eventually moving from strongly hardware influenced to purely software- and problem- defined. Just as we've developed abstractions and tools at the persistence ("filesystem") layer now, like snapshotting, similar tools will evolve to take advantage of the new hardware constraints.
The main obvious advantage of using non-volatile RAM across the board is that it won't consume power all the time, like DRAM.
