That's my exact experience with GitHub Copilot. Even boilerplate stuff it sucks at as well. I have no idea why its autocomplete is so bad when it has access to my code, the function signatures, types, etc. It gets stuff wrong all the time. For example, it will just flat out suggest functions that don't exist, neither in the Python core libraries or in my own modules. It doesn't make sense. I have all but given up on using Copilot for code development. I still do use it for autocomplete and boilerplate stuff, but I still have to review that. So there's still quite a bit of overhead, as it introduces subtle errors, especially in languages like Python. Beyond that, it's failure rate at producing running, correct code is basically 100%.
