> Unit testing won’t help you write good code.

This is factual and irrelevant. Writing good software is more than just writing "good code". Unit tests help reproducibility. They help orient contributors, too, as failing tests give clues and passing tests give comfort. Plus, if you have automation like Dependabot updating your libs, you want a basic sense of whether the fully automatic updates are sane from looking at the test results.
