Take a chessboard, for example. Now things get really interesting. Each square doubles the last, and the sums continue to grow. Each of these capabilities can be added to a modern desktop PC for around than R 600 each. 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.
