Moore's law applies to increasing IC density, not speed. His 3 Petahertz computer is obviously the result of considerable alcohol or drug use. Speed of Light: 3 X 10^8 m / s 3 Petahertz: 3 * 10^15 cycles / second Speed of Light / 3 Petahertz = 10^-7 m / cycle = 100 nm / cycle. Therefore this chip can be no more than 100 nm across - and that is being generous, as electrons are considerably slower than light. This is smaller than a single transistor on an Opteron today (130 nm feature size). If such a computer can be built, it will certainly not be using CMOS as we know it. There are other things on the horizon, but there is certainly no reason that Moore's law will apply to them. anthony
