The context for the author is game development. A game can't just spin up a few more servers in the cloud. The slower the code, the smaller the customer base. Some fields have more severe constraints, where developer time may be expensive, but compute is priceless. (This is not to endorse writing code that is harder than necessary to understand, or failing to document the parts that are necessarily hard.)
