This is the third and final change I would make ot the AI Fluency video. This is not on a specific video, but on the exercise near the bottom of the course. There is no submission. Someone completing this course could easily say they did this and get their certificate. Granted, they would be missing out on understanding the course more, but I think Anhtropic needs this to be interactive. There needs to be steps where you actually complete the exercise on the website, instead of doing the exercise on your own. This will make the course more effective and important to the audience, instead of skipping over the exercise to save time and get their certificate.
