I think the right way to think about this is the following: scaling "up" is basically over with CPUs. Now we need scaling "out". This means learning how to make use of many more smaller cores, rather than just a few larger ones. Here communications becomes the problem, and indirectly, affects how you design and implement software. Scaling is becoming a software problem: how can you take advantage of 1024 cores with just 64KB or memory each, in a world where terabyte-sized is the daily business? I think we will end up with systems with 64GB of memory, but which instead of 8 cores with 8GB each, have 1M cores with 64 KB memory each. We just need to lean how to write code that makes the most out of that, which is probably a lot more than what you can do with current systems. And this Epiphany thing is something like the first step in that direction. Exciting times.
