Moore's law is as much about economics as it is about shrinking. For all you code types, switching to a new device is not just as simple as fabricating a new chip in a research lab. Thousands of experimental devices and chips have been made in many research labs. Moore's law is about being able to consistently manufacture more and more millions (and now at billions) of very small transistors every generation (for silicon, this used to be about 1-1.5 years in the late 90's early 2000's).
