I'm not sure I spend less time actually coding stuff (because I have to review the Copilot code). But the cost of the code I write is definitely reduced, because:

- the review from my peers is faster (the code is more correct) - I come back less to the code (because I have thought about all the corner cases when checking the copilot code) - As I care more about naming & inline docs (it helps copilot), the code is actually cheaper to maintain.
