Pretty sure they meant to not have review. Dropping peer review in favor of pair programming is a trendy idea these days. Heh, you might call it “pairs over peers”. I don’t agree with it, though. Pair programming is great, but two people, heads together, can easily get on a wavelength and miss the same things. It’s always valuable to have people who have never seen the new changes take a look. Also, peer review helps keep the whole team up to date on their knowledge of the code base, a seriously underrated benefit. But I will concede that trading peer review for pair programming is less wrong than giving up version control. Still wrong, but a lot less wrong.
