They're not. Processor power is going to increase by # of cores, and all apps will be able to use multi-core efficiently. Look at "supercomputers" now, they're all multiple computers connected by fiber channel, etc. Power isn't going to increase by Ghz, its going to increase by adding more cores. In ten years, you'll start seeing processors that are clocked by the number of cores, not the speed. It will be like 512 cores or something.
