This is about the fourth time I've lived thru one of those consensus end-of-the-road forecasts for semiconductor feature sizes. Each time hey have gone past with maybe a years delay. Of course, lithography canny be extended forever, though it seems hard to predict the end of new techniques. As you point out,3disa way to go, and it has it's own problems, but there seems to be no hard physical limit to the number of layers one can add, presuming that defect rates are low enough. I'm really just Wanting two more generations of ssd, so that a 500 gb costs enough to not feel guilty buying it. From then on, it's gravy.
