It feels like there's fundamentally a tradeoff between "fast and flat" and "big". So basically I would guess NUMA and programming models that take it into account is the future. And maybe software management of CPU cache. I think wanting fast, flat, and big is sort of like wanting the CAP theorem to go away... "it sure would be great" if we could have an infinitely scalable SQL database without any programming model changes. In other words, no matter how "fast" a memory becomes, someone's going to want it "bigger", which makes things slower.
