For one function, yes. I used Copilot to do massive refactoring on my project recently - switch to a new JSON library, completely switch web frameworks, etc. The stuff I needed to do but was putting off forever. And even with small things, it's just toil. You can start a small update and then realize with all the back and forth of edit/test/edit/test that you've been stuck in the OODA loop for 40 minutes you will never get back.
