Visions of circuits and systems: circa 2100

Summary form only given, as follows. A hundred years from now, circuits and systems will be made of smart molecules operating in the quantum-mechanical regime. The architecture will be based Cellular Nonlinear Networks (CNN) where brain-like computation is consummated via the local activity principle. The systems will be self-assembled via bio-chemical processes. The author covers a broad spectrum of new concepts ranging from nonlinear circuit theory to molecular biology.
