Moore's law was simply an observation or a prediction about the computing market at that time: That the number of transistors on a chip would need to double every 18 months if the chip manufacturers hoped to get people to buy the next gen. He argued that people/companies wouldn't upgrade their existing equipment for a measly 10-50% increase in performance. They'd need to double performance if they wanted to get rapid turn over to the next generation of products.
