I definitely agree with the overall sentiment; one needs to be constantly on guard to maintain a good code base. I don't think it's just a matter of code review though. A bad team will take this "how to do a code review" and still produce bad stuff. A good team probably doesn't need "how to do a code review". The best code reviews I've participated in were more informal affairs. They're generally in person discussion rather than the distant commenting on some review platform.
