I would like to point out that not all ideas have been outpaced by Moore's Law, some obviously hit serious blocks after the barrier in the early 2000s was hit and caused the invention of multi-core on consumer machines. That I can personally attest to: 1. Simulation games are mostly stuck in power available since the 2000s, many common game algorithms can't be made parallel, and several algorithms increase in computing cost faster than processors increased in power since then (example: Astar, its computing cost rises quadratically with the search space, and the search space when you want to increase a game map size ALSO increases quadratically, thus to double a city simulator map size, you need to run A* 8 times the processing power... if you pay attention city simulators since SimCity 4 release tended to make instead smaller maps with more miscellaneous simulations). 2. CAD, CAE, etc... In this case the recent advances, including in GPU design made those software much faster, but they are still rather slow, if you need to compute a complex project, or even a simple project with greater precision, you still need some crazy powerful computer... As personal anecdote: I am trying to design a PC case for myself, decided to try my hand with CFD, first to test I made just a empty box with a "fake" fan, that is just a number saying how much air get inside the box... got a good result in 3 minutes. decided to test what happens if you have 4 fans side by side... well, this creates turbulence, thus need a more detailed grid to calculate that, the grid generation alone took 20 minutes, I decided to make half-assed simulation and the result was mostly nonsense. I decided then to test if I could model the entire fans, including their blades, housing, etc... I got a already done precise model of a fan, tried to generate a grid... and my computer overheated after 5 minutes using an i7 at 100% Of course, I knew I was "abusing" things, still, it became obvious to me that CFD for example, for anything "serious", is mostly impractical, if I had infinite money, I would still need to setup some kind of huge cluster or super computer, and the code to run CFD in that would be very complex, the thing is possible, but still impractical, even with infinite money.
