usually 'organization' excludes projects consisting of just one person, and if there are two people working on a project that involves writing code, the cheapest amount of that code for both of them to be familiar with is never zero, though it is often less than 100% of all the code they write. so i don't think that 'not all organizations can afford code reviews' is true, interpreted in the usual way. maybe you can be more specific about the scenario you're thinking of?

As mentioned in the other comments, code reviews are typically not done in the game industry, for example, or other write-once, never read scenarios. Very early stage startups typically don’t have formal code reviews either.

while that is true, and some of it is rational, other times it's just another stupid way people waste money and fuck up their projects. because even in a startup or a game there is code that people waste time debugging alone, or waiting for the one guy who knows it to get back from vacation, or out of bed

reviews don't have to be formal to be reviews
