In the 70yrs since transistor action was discovered, the industry motivated by the commercial opportunity that it presents, has created small and smaller transistors, and the methodology to connect them and utilise them in ever more sophisticated products. But today, as the size of the transistor approaches the size of the atom itself, the possibilities of further 'shrinkage' are obviously limited. And will this mean the end for the regular increasing sophistication of the electronic system products that we have become used to.
