EETimes a couple months ago spoke about current research (IBM Zurich maybe) into molecular flip flops...
There is potential for molecular gates...
With these two, you can create a revolutionary processor. Based on the size of a molecule, incredibly small wavelength operation would be possible.
In my opinion, that's technology on the cutting edge.
Too bad Americans, for the most part, won't be employed in the development or the production of the products, unless we fully convert to Communism that is. (end of political blurb ...every once in a while I actually say in public what I believe...)
