I have not reposted for some time, but this article struck a chord with my early studies in computer engineering. It highlights the limitations of Moore's Law and explores possible technologies for producing next gen computers!
I believe a new crop of chips replacing silicon will be invented one day, probably within the next ten years! Mankind has always stepped up to the plate and performed in the face of a challenge. Just look at the invention of the steam engine, the airplane, the rocket, and just how far we have come from the ENIAC in the 1940's to where we are in the evolution of computers.
