I don't think you've actually used it tbh. It's much quicker to read code than to write it. In addition, 95% of Copilots suggestions are a single line and they're almost always right (and also totally optional).

Here's how it actually works in practice

1. Start a line to do an obvious piece of code that is slightly tedious to write 2. Type 2 characters and Copilot usually guesses what you want based on context. Perhaps this time it's off. 3. No matter, just type another 3 characters or so and Copilot catches up and gives a different suggestion. I just hit "tab" and the line is complete

It really shines in writing boiler plate. I admit that I'm paranoid every time it suggests more than 2 lines so I usually avoid it. But in ~year of using it I've run into Copilot induced headaches twice. Once was in the first week or so of using it. I sweared off of using it for anything more than a line then. Eventually I started to ease up since it was accurate so often and then I learned my second lesson with another mistake. Other than that it's done nothing but save me time. It's also been magnificent for learning new languages. I'll usually look up it's suggestions to understand better but even knowing what to look up is a huge service it provides
