    I don't think it will end anytime soon.

    We're running out of time for normal transistors, though. Modern computers run at around 3 GHz. That's 1/3000000000th of a second per clock cycle. In that amount of time, light could go about 10cm. I'm not sure how far electrons have to travel in a CPU per clock cycle, but if you consider that our transistors are already only 32nm in size and probably won't get smaller than 1nm any time soon, we're probably reaching the physical limitations of transistor-based computers.

    That said, it'll always be able to increase computers' speeds in other ways. Larger caches, faster RAM, faster buses, more efficient chip layouts, more cores, and optimizations in scheduling and cycles-per-operation will allow us to make faster and faster computers for a long time to come.
