Turns out that the company isn't done trying to reformulate and revive ideas it has already tried before. As part of a push toward what it calls "human-centered AI," Microsoft is now putting a face on Copilot. Literally, a face: "Mico" is an "expressive, customizable, and warm" blob with a face that dynamically "listens, reacts, and even changes colors to reflect your interactions" as you interact with Copilot. (Another important adjective for Mico: "optional.")
