In earlier days, this used to be a fairly common attitude for sysadmins. The context then was different - systems were a lot more expensive and energy consumption wasn't considered at all. The argument was, basically, you can't save cycles. You get so many per second, whether or not you use them. And not using a machine you dropped mid-six figures for seems like a terrible business waste. Vastly cheaper machines, ecological crises, battery powered devices, and security eclipsing performance in importance changes that analysis a lot.
