Moore's law is more about what happens when you get a lot of people working on a clearly defined problem + network effects where a new breakthrough helps everyone else get nearer to another breakthrough. This is why you find Moores law in so many places. It studies rate of change in technological progress.

In a particular area (eg, single core cpu performance) it eventually follows a sigmoid curve (where all hockey sticks must go) as lower hanging fruit exposes itself (eg, higher parrallelism and GPU computing).

Kurzweil (say what you will) has written a lot on the topic.
