Yup. Also code review is not just there to check your work. It's forced communication, in that at least someone else knows about the changes you're making.
It's also a critical part of your security model. "Nobody can deploy code by themselves" is shockingly effective at preventing rogue actions.

Speaking of communication... Almost no one mentions talking to non-devs. That's one of the reasons I can't just rely on any of these tools, I have to remember and understand everything well enough I know how they work and can explain things and help plan ahead when talking to product people in meetings.
