> If you had a button that switched on a thousand washing machines at a time I guess one could flirt with the title "washing engineer". Since that button probably wouldn't work correctly 100% of the time, the operator would probably be forced to learn about problems and solutions related to that activity. Over time, that person would accumulate experience and knowledge which would make them well suited to that simple job of flipping the switch on and off. And at that point, that person would be more of an engineer than a random person who walked up and flipped the switch. An _anything_ engineer is just someone who does that thing and the unnamed related things necessary to do the main thing.
