Moore's law will continue the second we drop silicon and start using electrons as gates.,(reply>), Just, raw electrons?<br><br>Silicon substrates are where electrons are channeled in most IC/CPU designs.<br><br>There are alternatives, GaN(Gallium Nitride) is the most promising currently operating much wider range of temperatures (400-500C being possible, presumably ideal for harsh environments and space missions to other planets), but the electrons are still channeled into a substrate.<br><br>Albeit, you could argue that silicon or GaN molecules also have electrons, and while you might be right, I am unaware of any engineering processes which are aiming for a pure electron computational model devoid of substrates entirely.
