> Why do human programmers need code review then if they are intelligent?

Human programmers don't need code reviews, they can test things themselves. Code reviews is just an optimization to scale up it isn't a requirement to make programs.

Also the AGI is allowed to let another AGI code review it, the point is there shouldn't be a human in the loop.

> And why can’t expert programmers deploy code without testing it?

Testing it can be done by themselves, the AGI model is allowed to test its own things as well.
