What will happen when Moore’s Law can no longer apply?

Moore’s law describes the trend for the number of transistors that can be placed on an integrated circuit to double roughly every two years. One of the sexy new technologies is optical computing where particles of light rather than electrons whiz around devices. Optical devices are faster than their traditional electronic predecessors. But creating channels for light at the nano-scales needed for chips is proving to be a challenge, limited by the wavelength of light.

That said, scientists now reckon they have materials in which the light skims the surface rather than having to travel right through. It could be one of the techniques for ushering in a new generation of super fast, miniature optical processor

Another exciting area is quantum computing. It exploits the weird condition where information can be in two states simultaneously. Great in the lab, but they just need to replicate it in real chips, mass-produced, for us to buy.
