I would suggest that when someone wants to get excited about exascale computing, they review the Connection Machine literature. Manycore is not a radically new concept.
The fact is that the GPU (and the many micro cores) will be consumed by the cpu instruction set in the long run. Yes, that means we're going back to frame-buffers.
