Yes, scaling down silicon based electronics gaining in speed, but only until certain limits which have silicon to scaling down the components, currently un atomic scale. Because of this are investigated other materials, like syntetic diamonds, which soports much more heat and with this a major processing speed. Quantum computing ofrfers much more speed, because it isn’t limited to 1 OR 0, it can process simultaneous 1 AND O AND everything in between, until now the difficult is that it need very low temperatures and the lack of stability with minimum interferences. But technology is advancing and cooling by magnetic means makes it possible to dispense with nitrogen/helium cooling and allows its application in desktop PCs, although at the moment only with three Qbits, suitable for both research and education use for complex calculations. Well, with the first PCs the same thing happened.
