> A good goal as a developer is a high commit message to change ratio. The more lines of code that you change, the more comments explaining why you’re changing the code. More message and less code changes per commit is generally a good idea.

No! Blanket statements like this is how you end up with 40 pages of slop AI comments in PRs that nobody reads.

Comments should be terse and meaningful. They should document surprising behavior or choices. The less comments you have, the more meaningful each one becomes because your time and eyeballs are limited as well.
