I think the part that often gets overlooked about code review is that it is useful for maintaining knowledge of the codebase for the reviewer.
I know our codebase like the back of my hand specifically because I'm reviewing almost every PR going into it.
I've realised that agents are doing better code reviews than me lately, they can catch more logic issues, performance issues, etc. Now, I focus on whether the intent/objective is addressed and leave the rest to a review agent.
Honestly, when the context is set up properly, GPT’s top models are just smarter. That’s been true for a long time.
