If it's an assistant that you constantly have to double check their work, then they would get fired ASAP.

That's the problem with Copilot. If I'm not familiar with the API calls then I'm still going to have to dig into the docs. I could run it and it might "work", but that doesn't guarantee that it's correct. There are a whole lot of things in the C API that work but are not correct, such as the gets() function. If I have to do such legwork then it's just as easy to write the code myself.

The utility of AI is proportional to the trust one has in it. Trust is easy to lose and hard to regain. It will take just a few AI mishaps to ruin a product or even an entire industry.
