Also one really good practice from pre-Copilot era still holds, that many new users of copilot, my past self included might forget: don't write a single line of code without knowing it's purpose. Another thing is that while it can save a lot of time on boilerplate, you need to stop and think whenever it's using your current buffer's contents to generate several lines of very similar code whether it wouldn't be wiser to extract the repetitive code into a method. Because while it's usually algorithmically correct, good design still remains largely up to humans.
