We had MS reps give a demo of Copilot chat for our company recently. I was already using it for autocomplete but lemme tell ya, chat is something else!

If I want a refactoring or feature change, I can just swipe over the function or line of code that needs changing and tell chat to do it! The written function appears in the chat window so I can read it or copy it. That has been huge for small, ugly changes that are error-prone and I don't feel like making myself or looking up syntax for.
