Can living cells become computers? Can billion-component molecular chips be made cheaply - in a beaker? Is there a limit to chip speed? The latest issue of Technology Review explores the future of computing as the industry moves beyond silicon. Feature articles examine exotic approaches based on DNA, individual molecules, cells, and quantum properties. Plus, the corporate logic behind funding silicon alternatives and a Q&A with Hewlett-Packard CEO Carly Fiorina. Columns focus on easy-to-use machines, the e-book copyright debate, Bill Gates' future, and the search for smarter searches.
