We, engineers, consider ourselves smart and most likely are open to prove it to others, don’t we? Should I still practice code review, even if it takes a lot of time, and my code probably will not become that bad if I resign? Of course, the possibility of conflicts depends a lot on the individual character of developers, but if it happens, there are few rules, how to reduce it in the future. Rather than having a reviewer spend 15-30 minutes reviewing a change that took one developer a few days to make, in pair-programming you have two developers on the task the entire time.
