No, it's not "Moore’s Law predicts the doubling of processor speed every 18 months.", even though you'll see that description all over the place, such as Durig Capital LLC's page called Monopoly Articles.
What is the real Moore's Law?
For that, go to the "source" on the Intel website, to wit:
"Moore observed an exponential growth in the number of transistors per integrated circuit and predicted that this trend would continue. Through Intel's relentless technology advances, "Moore's Law, the doubling of transistors every couple of years", has been maintained, and still holds true today. Intel expects that it will continue at least through the end of this decade. The mission of Intel's technology development team is to continue to break down barriers to Moore's Law." [emphasis added.]
