Silicon technology-in the chips for the future?

Transistors made from silicon have dominated solid-state electronics for three decades, creating a multibillion dollar industry that has revolutionized modern life. At this stage in silicon's evolution, however, some observers doubt that silicon's dominance can continue.

The author assesses exactly what one should believe about the future.<
