&gt; insanely exorbitant costs<p>wat?<p>Either the code is easily readable and correct, and takes barely any time at all to review, or it&#x27;s buggy and detecting this early rather than late saves a yuuuuge amount of time.<p>Also, the reviewer now knows the code. So in reviewing the code they&#x27;ve already half way to being able to improve the code in the future.<p>And the reviewer can also pick up &quot;oh, that&#x27;s a neat pattern&quot;. Code reviews are education for both parties. Are you saying companies should not spend time or money on education&#x2F;courses?<p>And as an author I really appreciate not only that someone looks for me having made a mistake, but because I know someone will read the code I won&#x27;t go with the easy way. I can fool myself, but I can&#x27;t fool someone else. E.g. the right thing to do is to name this constant or make an enum, but I&#x27;ll just put a literal &quot;4&quot; here because I know it&#x27;s 4. (which of course I won&#x27;t remember in a week).
