The article didn't well on Dark Silicon but the idea is that as you can fit more structures on a chip but can't light up them all for power dissipation reasons it makes sense to include more and more specialized structures you only use for some purposes. With the rise of GPUs and specialized co-processor for things like media decoding and encryption we're certainly well on our way there. It would be nice to have an intermediate between the two in more places, like the Hexagon VLIW DSP that Qualcomm puts in its Snapdragon DSPs. And of course there are the even more specialized matrix convolution processors that everybody is designing and NVidia is now putting in its GPU. I think the real question is if it will make sense to have FPGAs in wider use. Certainly not until the programming model improves...
