My brother sent along an EE Times article about new developments in computer chip design, and prefaced it by saying:

Here is a short article describing simple overviews of where the semiconductor business is going in the next few years. As the article shows, current methods of fabricating chips are reaching a performance and economic limit, but new ideas and techniques are being developed to take the place of what has been done in the past. These changes will go unnoticed by consumers but are large complicated steps from an engineering standpoint. So the life of pure silicon chips will be gone shortly.

Pure silicon, we hardly knew ye.
