Moore's Law actually refers to the density of transistors on a chip doubling approximately every two years, not CPU speed. Yes, CPUs still get exponentially faster, but this affects multi core throughput, single thread performance improves way slower. For human perception and interactivity, this makes a huge difference. So it stands to reason if algorithms would have been parallelized earlier and better, but I doubt that the timeline would just be shifted a few years.
