> We're all focusing on the weaknesses of co-pilot (the comments can be longer than the code produced; you need to understand code to know when to elaborate your comment, etc).

See, this tells me you may not have even used copilot. Because while tutorials such as this (and the OpenAI codex tools) have you use comments explicitly to code, the reality is that you're not hammering out plain english requirements for copilot to work. You just code - and sometimes it finishes your thought, sometimes it doesn't. You hit tab to accept autocomplete, just like you would for any other autocomplete. So you are generally reading and evaluating what copilot thinks is a good output and choosing whether it goes in the program or not with the TAB key.
