Experts are expensive. And there's hubris or what I jokingly like to call the maxim of management myopia: "Anything I don't understand must be easy."
So much this.
I know of a case where a company hired a junior java dev for a desktop project and after his second week on the job the manager posted a ticket instructing the newbie to implement a component to receive a video stream from a drone, stitch the video stream into a 3D model, and render the 3D model in real time. "How many days do you need to finish this?"
