After 60 years of doubling computer complexity every two years, can Moore’s law still predict the future power of the devices we use?
In 1965, electronics pioneer Gordon Moore was asked to predict the next ten years of progress with the then new-fangled silicon integrated circuits. He estimated, based on physics and manufacturing technologies then available what seemed remarkable: that every two years they would double in complexity, and halve in price, until 1975.
60 years on, perhaps the even more remarkable thing is that they just kept doubling.
Can Moore’s law hold into future decades? What are the next technological innovations that might keep it running?
Sri Samavedam is the vice president for silicon technologies at imec in Belgium, whose job it is to think about the practicalities of manufacturing the next generations of chips years before they become real.
Scott Aaronsen of the University of Texas is a thinker in the field of Quantum Computing – could quantum computing keep the rate of growth going? Or does it need to be thought of differently?
One of the limitations on chip miniaturisation is the dissipation of heat from conventional electronic flow. Nick Harris of Lightmatter is looking at using photons rather than electrons to carry info and logic around a circuit with lower power losses.
Stan Williams has spent much of his career thinking about new devices that could be fabricated into integrated circuits to give it all a push forward. And he tells Roland how the memristor could effectively bring the power of analogue computing to bear as we reach some of the limits of the digital age we have been living in.
