ChatGPT doesn't "know" anything, at least not the way you think. Every time you hit enter, it plays a guessing game: one tiny piece of text at a time. In this video we catch it in the act, with a live-style next-word demo, and break down tokens, training, attention, hallucinations and the hidden "temperature" dial, with zero jargon. My take: the biggest mistake isn't thinking AI is dumb or thinking it's alive. It's treating a brilliant improviser like a search engine. Use it as a first-draft partner, and be the editor yourself.
