So what, does this mean we're going to be seeing computers with 40 TB of RAM, 1000000 TB of hard drive space, and video cards that can render the highest quality renders in less than a second?
The processor is the part that does most of the actual calculations. That's the part that would benefit the most. Graphics cards do have their own processors, too.
Unless I'm mistaken, modern Hard drives and RAM probably won't be affected very much.
One thing that this means is that the "memory wall" problem will only get worse. CPU speeds have been increasing at a much faster rate than memory, and memory access times haven't been able to keep up with increasing clock frequencies, creating a performance bottleneck. Recently, advancements in CPU speed have slowed due to certain physical barriers (namely, the fact that transistors can only become so small before they reach the atomic level, which is currently not feasible) but if this article is to be believed, than those barriers are on their way to being broken.
