Believe me, chip designers care more about power now than they did then. Back in the larger process nodes when you moved to the next node the voltage scaled also, and as power is proportional to voltage squared, power went down. It was the ultimate free lunch, smaller, faster, lower power. That mostly ended around the 20nm node. Now designers work very hard to make things more power efficient, or stay within a thermal budget.
