Why do so many people in this forum not understand the article. He is not literally inventing work. He is finding out what work needs to be done by reading the signals. Users and customers don't often know or care about the requirements of your system (are users and customers going to tell Facebook what it needs technically to handle a surge in users for its new AI that gives everyone on Earth a private VM to mess around in?). That's why you hire engineers. To figure out what needs to be done to keep serving the product, which is what users actually care about.
