It does a bunch of useful things already. Arguably most users of Copilot see it as having a positive contribution or they would not pay the price. Generative Image models are pretty good at fixing photos and creating vector art. Chatbots, even though they hallucinate, are consistently polite, helpful and efficient. They are good at sparking new ideas, playing fantasy games, debugging and rubberducking. Maybe they are also good therapists, when prompted right. They are universally used for summarisation, text based question answering, and extracting data in JSON.
