How big/complicated are the functions Copilot is autocompleting for you? I'm thinking perhaps reading 10 potential candidates is actually slower and less instructive than trying to write the thing yourself.
You can actually see all the code blocks Copilot is thinking about if you want to, but that is indeed a distraction.
Based on the FAQ, it looks like some information about how you interact with the suggestions is fed back to the Copilot service (and theoretically OpenAI) to better improve the model.
So, while it may not understand "how to make code better" on its own, it can learn a bit from seeing how actual devs do make code better and theoretically improve from usage.
Do you have examples of what the line ones can do? The site doesn't really provide any of those.

https://github.com/HackerNews/API doesn't list this as a valid endpoint. Indeed, when I try to access it via curl, I get a HTTP 405 with a "Permission denied" error (same result when I try to access nonexistent-endpoint.json).
Based on the HN search on the website, I'd expect the correct autocomplete to involve hn.algolia.com [0].

To me, this points at the need for human input with a system like this. There is a Firebase endpoint, yes, and Copilot found that correctly! But then it invented a new endpoint that doesn't exist.
