I'm afraid that processor speed is going to plateau sometime in my lifetime.
Probably shortly, apparently we are already getting to the point where we can't make chips any smaller, hence the multi-core processors. I read some article a while ago about light based processors, and the potential future for doing anything with light. They said they could get something like 3 terrahertz speeds with a light based CPU, and that companies were already working on such technology. I think we will easily see a breakthrough in our time.
Who knows, we may hit a technological singularity this century.
