The point is not to fetishize comments. Write a comment if you feel something needs explanation, but don't freak out about "uncommented code" as a smell or whatever, when reading the code should have been your first step anyway.

And to repeat: when debugging, train yourself to ignore the comments. They will absolutely lie to you.

Imo comments are like formatting. If you don’t enforce it in CI it’s going to be bad

Forcing developers to write comments[1] just to get code merged seems like the best possible way to ensure those comments are lies.

[1] Which, it's important to point out since you used the term "CI", are fundamentally untestable. There's absolutely no way to ensure a comment is correct. A CI smoke test at the very least verifies code builds and doesn't break pre-existing cases. No such validation is even theoretically possible for comments.

I’ve seen it done before and no, it was beautiful, everything was commented
