Not to mention putting the RAM directly on a System-in-Package chip like Apple does now. That's going to be unbeatable in terms of space and possibly have an edge when it comes to power consumption too. I wouldn't be surprised if future standards will require on-package RAM.

I kind of wish we could establish a new level in the memory hierarchy. Like, just make a slot where you can add slower more power hungry DDR RAM that acts as a big cache for the NVM storage, or that the OS can offload some of the stuff in main memory if it's not used much. It could be unpopulated in base models, and then you can buy an upgrade to stick in there to get some extra performance later if needed.

This is kind of what Optane was in some incarnations (it's really terrible branding that conflates multiple technologies).
