Goal of pair programming isn’t better quality code, that is a side effect, but better quality solutions. It’s one of those 1+1=3 types of things.

It is also a great training tool. Can’t tell you how many times I’ve had junior engineers ask me about something that I thought was common knowledge or wouldn’t have thought to mention cause I thought it was trivial.

It’s a tool in your toolbox. Don’t use it on every problem.
