What comes after we hit the 16nm barrier?
mnemonicsloth: Moore's Law isn't going to die.  It's going to be extended, (or supplanted) by further developments, like Einstein's gravitation extended Newton's.There are many, many successor technologies to CMOS out there:  nanotubes, nanowires, magnetic switching, molecular switching, photonic switching.  I'm sure more have been proposed in the five years since I stopped paying attention.The situation for semiconductor researchers and manufacturers is a lot like the one Edison faced with the light bulb.  We know what we want, and there's a huge field of options open in front of us.  Now we just have to spend some time on basic research to figure out what scales and what doesn't.  This might take some time, but a delay will only make the next doubling more lucrative when it becomes feasible.And if you're comfortable with (only slightly) more far-out ideas, the wall is being written right now:http://metamodern.com/2009/05/22/a-third-revolution-in-dna-n...It so happens that this development has been anticipated here:http://e-drexler.com/d/07/00/1204TechnologyRoadmap.html
