Code review isn’t a singular thing. There are many reasons for code review, like knowledge sharing, liability laundering, code quality, regulatory compliance, etc. As usual, what purpose it serves depend on your use case.

Thank you! I find it somewhat ignorant to say, most people do not understand the reason behind a peer review, while obviously being missinformed. To even believe that it only serves a single purpose somewhat tells me, that the author is missing experiences with other teams / people.
