As Moore's Law continues its march, the simulation and modeling tools that you use to design and test the circuits are struggling to keep up. We're doing better now than we used to. Now we know how to work, and we're paying a lot of attention to it. So for your purposes they are keeping up. We all would like to have more, of course.
Processing power can substitute for bandwidth to a significant extent.
For example, you can send tolerable video over ordinary phone lines so long as you have enough processing power to compress and decompress the images. So in some respect they're complementary. But I look forward to the day when we all have gigabit pipes coming into our houses. There's obviously a lot of industry work going on to try to make that available. It looks to me like it's going to come from a variety of different directions.
