Computer hardware innovation is a textbook example of diminishing returns. With each improvement in processor performance, size, energy usage, and heat management, it becomes more expensive to push the tech further. We're currently witnessing this effect in action with the recent stagnation in consumer processor speeds. They are still getting better in size, energy and heat management, but average speeds have hovered around 2.5Ghz for years now.
