Michael A. Nielsen and Isaac L. Chuang (2004) wrote in their book "Quantum Computation and Quantum Information" [ISBN 0-5216-3503-9] on page 4:
"One possible solution to the problem posed by the eventual failure of Moore's law is to move to a different computing paradigm. One such paradigm is provided by the theory of quantum computation, which is based on the idea of using quantum mechanics to perform computations, instead of classical physics."
Another such paradigm is provided by the theory behind Pile Systems (see www.pilesys.com). Peter Krieg's paper "The Red Brick Wall" deals with technology trends in the computer industry and their implications in relation to Pile.
