If you think (as many do) that there is a simple algorithm for intelligence, then scaling up is just a matter of optimizing the software and hardware and making more of it. And if the AI has the capacity to reproduce itself (either by installing itself on commodity hardware, or by building automated factories, etc) then it could grow from a seed to a superintelligence very quickly.
