"Silicon forever! Really?"

With certainty scaling in silicon is going to hit a wall - technologically or economically. While we do not know exactly when this is going to happen, "approximately a decade from now" is a pretty common guess. Hence it is prudent to contemplate and investigate alternative ways to create electronic systems that may have a chance to lead us "beyond silicon". At present there is no clear path at all. Only open-minded and imaginative research has a chance to overcome the foreseeable impasse.
