Yes. Stuff only needs to be fast enough to be barely usable. It's a simple economic principle. Making programs faster need not be hard. When looking at programs I often think how easier it would have been to organize them right, so they would be both easier to make and faster to run. However, this requires more experienced engineers, which are a scarce resource. So we're back to economics.
