Abstract

Each year's new computing technology, it seems, leaves the last year's in the dust. But physicists are now beginning to tell computer scientists that it can't go on this way. Sooner or later, as computers get smaller, faster, and more complex, the laws of physics will throw up roadblocks to further progress. There's only one way out of this bind: radically new strategies. And some of those strategies are starting to emerge.
