Just so you know I manage 6 people right now and we are doing quite well. The sort of yours would not be welcome for sure. People who cannot think out of the box will always be boring and predictable.

If you cannot imagine a world where code reviews don't help at all it shows your lack of experience. Work 10 more years in 8 different companies as I did and you will quickly learn that what you say has no grounding.

Being correct and kind is cool. But it won't get you anywhere.
