ELI5 — The Vibe Check
ChatGPT is the app that made AI mainstream — it's the iPhone moment for artificial intelligence. You chat with it like texting a friend, and it writes essays, debugs code, explains quantum physics, and plans your meals. Before November 2022, most people thought AI was just self-driving cars and robot dogs. Then ChatGPT showed up and suddenly everyone's grandma was using AI.
