A four-panel xkcd comic shows two stick figure characters: one standing and one sitting at a computer. Panel 1: The standing character points to a small box on the floor with a cord coming from it. Standing character: “What’s this?” Sitting character: “The cloud.” Panel 2: The standing character looks confused. Standing character: “Huh? I always thought ‘the cloud’ was a huge, amorphous network of servers somewhere.” Sitting character replies: “Yeah, but everyone buys server time from everyone else. In the end, they’re all getting it here.” Panel 3: The standing character asks: “How? You’re on a cable modem.” The sitting character responds: “There’s a lot of caching.” The standing character, now looking at the long cord stretched across the room, asks: “Should the cord be stretched across the room like this?” Sitting character answers: “Of course. It has to reach the server, and the server is over there.” Panel 4: The cord stretches across the floor between them. Standing character: “What if someone trips on it?” Sitting character: “Who would want to do that? It sounds unpleasant.” Standing character: “Uh. Sometimes people do stuff by accident.” Sitting character: “I don’t think I know anybody like that.” (alt text by ChatGPT)
