Not that I agree, but I think the concept is that if we get human-level cognition on day x, then that cognition will be used to design improved processors as well as improved cognition. In x+18 months, the cognition has doubled in power, and so has the processor. Which means that the next iteration happens at x + 9 months. (I don't know how he gets from 18 to 12. Maybe he's figuring that cognition increases less quickly than processors.)
