You just finished How AI Works.
The whole lesson comes down to one line from the transcript: "You give it some text, and it guesses the most likely next word, then the next, then the next."
That's it. No magic.
Now prove you've got it. Reply with two things:
1. Your one-sentence explanation of AI, written for a friend who knows nothing about it. No jargon, no hype. If your sentence contains "tokens" or "neural network," try again with plainer words.
2. The term that confused you most before this lesson (agent? RAG? MCP?) and what it actually is now, in your own words. Do the term-matching worksheet first if you haven't.
Why this matters: if you can explain it simply, you understand it well enough to build with it.
That's the test, and it's the last thing standing between you and choosing your path.
