Completely agree. I'd only add one point: Quantum computing -- when and if we ever build them with enough error correction to be practical -- can replace GPUs for a few very specific kinds of search where the statistical shotgun approach that quantum computers do so well can be exploited. One canonical example is the quantum FFT (Shor's algorithm) which seems to work quite well for finding the factors of large composite numbers.

Quantum computers are not magic and they are by no means general-purpose, but if your search mechanism matches the kind of search quantum computers are good at, they can greatly exceed the speed of GPUs.
