And computers just keep getting faster. Expert opinion is mixed. It's pretty clear that chip manufacturers are reaching the limits of what physics allows in terms of making smaller and smaller components. Sometime relatively soon, it will simply be no longer possible to add more transistors to a chip. This doesn't mean that computers won't keep getting faster, however.
New techniques are already in development to increase computer power.
In the next decade we'll see the emergence of computer chips based on new materials, chips shaped like spheres instead of flat squares, perhaps even chips using computing methods borrowed from studies of the human brain. In the decades beyond that, exotic notions such as DNA-based computing and quantum processors could well lead to incredible breakthroughs. In many respects, Moore's Law is the underlying engine of the computing industry. For business, faster computers can mean getting an edge on the competition, with better control over business processes and more sophisticated models of the future. These are the kinds of questions that we and our children will be forced to answer.
