You don't become a good editor, inspector, what have you, by having other people/machines write all the code for you. To become and, perhaps more relevant, to stay a good reviewer, you need to regularly write code from scratch to see how it works. On top of that, languages, frameworks and libraries change constantly and you need to write and execute and experiment with new code to see exactly how it behaves so that you can eventually review the code that uses these features. Good reviewers are not born good reviewers!
