The principles governing increases in computing power could be sustained into the foreseeable future thanks to UK-based research that is applying advanced metallurgical techniques to magnetic semiconductors. Moore's Law is the observation that the density of transistors on an integrated circuit doubles every two years. To achieve this, components have shrunk over time, but scientists anticipate that when nanowire parts go down to around a tenth of a nanometre, heating and quantum effects will become so severe that they will not be of practical use.
