Why do Claude and ChatGPT both cost $20 a month? Asked Opus 5.5 to explain it with Nash equilibrium. First it used the prisoner's dilemma. Correct, but I still didn't get it. So I changed the ask: explain it like I'm 5, with things I already know. The version that worked: 2 ice cream carts on a beach, then the $20 price tag. Took 3 tries. Clicked in 2.5 minutes. The prompt, for any concept: "Make a 2-3 minute whiteboard video explaining [concept]. Explain it like I'm 5. Start with one everyday example I can picture, then connect it to something current I already know."
