I disagree,Ion Todirel said:by the sound of it, it will never happen, quantum computing ftw
Consider, "never" is such a strong word. It goes in a category with "hate", one should use words like these wisely.
Moore would probably also disagree: http://en.wikipedia.org/wiki/Moore's_law
See transistor count chart: http://en.wikipedia.org/wiki/File:Transistor_Count_and_Moore%27s_Law_-_2008.svg
Now consider this. With transistor counts on a continual and exponential rise, even a nominal frequency tolerance shift would give substantial gains.
