That’s a little bit of a No True Scotsman. Yes there are people who do not review anything; but even people who are reviewing every line from an LLM do not have the same understanding as someone who wrote it themselves.

I’m not making a judgement call about which is better, but it was widely accepted in tech before the advent of LLMs that you just fundamentally lack a sense of understanding as a reviewer vs an author. It was a meme that engineers would rather just rewrite a complicated feature than fix a bug, because understanding someone else’s code was too much effort.
