(Tremendous hubris warning, please correct me if I'm off base with where I go) Moore's law doesn't include capital investment as a factor. Initially, it could be mostly ignored as it was swamped by available profits (at least for microprocessors, less so for memory). More recently, I believe it's been matched by increased volume of semiconductors used throughout the global economy. But at some point we'll reach saturation. And costs to shrink feature size will continue to increase exponentially. So it simply won't make financial sense to continue. (Unless non-silicon, non-electrical, or radical patterning technology hits a breakthrough)
