These days everyone is talking about the limitations of silicon and the demise of Moore's Law by 2015 (e.g. I heard Anderes Heljsberg talking about the use of C# in Parallel programming and he used the term 'Desmise').
Recently Intel published an interesting article about the Moore's law and how Intel is developing new technologies to provide more and more computational power.
Take a look at the article: From Moore's Law to Intel Innovation—Prediction to Reality.
One more interesting thing is a video in which Gordon Moore himself explains his lecture. However I am not yet able to download it. See the flash movie. I saw that and its great.
The links to both of these are at the bottom of the page.
