I don't know about Copilot itself but I agree in general large language models will also bring a huge change like computers, internet or smartphones did. Large language models are still in their infancy as they get better and more people learn how to use them. They will bring a huge change to how computers/smartphones are used by the majority of the people not just the tech inclined. People that mostly use their computers/smartphones just tiktok Facebook and YouTube etc will use it for a lot more as the interface for computing for will change dramatically.
