It saves me a decent amount of rote implementation. I read up on the APIs, I understand the pattern I'm supposed to implement, but then Copilot actually does it for me. It's not a world-changer, but it does save time, it does "help".
And not for nothing, at least once I've pasted a script into GPT4 and asked "What's wrong here?" and it correctly identified I was using `[` instead of `[[` for a Bash conditional. This was code that had been working for years (AWS must have updated what version of Bash it was running CodeDeploy through), I never would have thought to check something like that. Realistically saved me an entire day hunting that down.
