I have not used it, but I don't understand how copilot could be useful. As a game programmer I don't spend much time actually writing final code. Most of my time is spent working stuff out on paper or writing little tests which I will discard.
In general I want to write as little code as possible as more code = more problems. The code I do write I want to put great care and craft into in order to keep it maintainable. Giving up any of my agency in this critical area seems like a terrible idea to me.
Something that will help me write more code, or write code faster is of no benefit to me.
