predicting the outcome of 5 more years of bleeding edge technological development seems fanciful.
Ever heard of Moore's law? Not quite up with the Higgs Boson, but still one of the most startlingly correct predictions of future progress.
Once CMOS and VLSI fabrication were working, Moore's law became inevitable. It was based purely on the physical scaling laws. Prior to CMOS, engineers talked about the "smoking hairy golfball" problem: a CPU with the sort of performance we take for granted today, would have to be the shape of a golfball because of the speed of light, hairy with wires connecting to it, and smoking because there would be no way to get many kilowatts of heat out of it.
But CMOS scales at constant power per area of chip, so Moore's law worked until the minimum size of a channel became limited by the discrete size of atoms. We're pretty much at that limit now, with Flash and Intel's FIN-FETs.
