How is that different than suggesting that all the engines we've ever made should constantly be driving load? It may not be obvious in the same ways as engines

How is that different than suggesting that all the engines we've ever made should constantly be driving load? It may not be obvious in the same ways as engines, but computation consumes a resources like power and attention and outputs waste like heat and fried circuits. These resources and wastes interact with other systems than just computers and data centers and so efficiency and necessity needs to be considered in a bigger picture than just "let's use all the transistors all the time and see what happens!"
