Sometimes, Copilot is brilliant. I have encountered solutions that are miles better than anything i had found on the internet nor expected to find in the first place.
The issue involved heavy numerical computation with numpy, and it found a library call for that that covered exactly my issue.
I've had similar experiences. Sometimes it just knows what you want and saves you a minute searching. Sometimes way more than a minute.
But I find it also hallucinates in code, coming up with function calls that aren't in the API but would sound like a natural thing to call.
Overall it's a positive though, it's pretty easy to tell for your other coding tools if the suggestion is for something made up, and the benefits of filling in your next little thought are very real.
