At another level, code reviews also give you the time to really think about what is being built and why. I've often come across looming architectural or strategic failures simply by having to stare at a bunch of code and wonder why it works a certain way. Same goes for writing the code by hand too, though it's harder to see past your own biases and ideas sometimes. I find code reviews deeply valuable for myself and my team.

Yes, I could hunt cockroaches all day, but it would be even better to have caught how the new wall was missing a metal screen over a low ventilation opening.
