It's funny you bring this up because people opposed to `.unwrap()` usually mention methods like `.unwrap_or` as a "better" alternative, and that's exactly the equivalent of `??` in Rust.

Semantically the two are kind of opposite; the similarity is that they're the lowest-syntax way in their respective languages to ignore the possibility of a missing value, and so get overused in situations where that possibility should not be ignored, leading to bugs.
This is exactly what I was trying to communicate in the article. You've put it in a way clearer way here though. Thank you:)
