Loved this. And I agree with most of it.

One thing I disagree with (and I know this puts me in the minority) is code review.

Code review for trusted engineers is a waste of time. You're only going to find those bugs that are very hard to see. And the odds of you catching them in code review are very low. Also, if you're a kind of fast moving startup (like my company is) there's so much new code coming through that it is a serious slowdown to review it all. At least at the level where you'd need to if you're going to catch the things that the original author missed.

I only make juniors and new hires do code reviews. I'll also ask for code reviews if an engineer is taking on a task that's totally new for them. But otherwise we've totally cut them out and been fine.
