Well in a way it could be. I'd read the spectrum article some time back, but since I work in the field I can give some insight.
RAM latencies are a huge hit for applications that are based on random access. DRAMs etc. don't actually do random access the way you'd want they access one memory over a large time period, and provide faster access to some successive elements. New processor architectures based on smart caches and intelligent memories could be a lot more useful, basically though a rethinking of processor architecture is involved - in the end electrical and computer engineering is still that : Engineering there will always be tradeoffs.
