https://experiments.withgoogle.com/ai-duet "A piano that responds to you." This is a project called AI-duet in the AI Experiments by Google collection. I chose this one because even thought it is relatively simple comparing to other projects I browsed, this one for some reason really connected with me. We are always thinking about how ML can help us do things that we don't or cannot do, but in this project, there's this connection you build with the "other person" inside the screen that listens and responds to you. In some sense this is a new method of communication between people and a machine, which I only find to be adorable instead of weird as I would have expected. The way that it "listens" is super intriguing. I think this is actually the first project which I really loved the simplicity.
