I think the newbie coming to the fancy pancy hubernates cluster company in 5 years when you and the other engineers have moved on will have a complete new level of headache inducing mess to deal with compared to what you had at the boring company as a newbie.

I started out my career thinking best practices with agile, code review, CI and "shared ownership" and stuff were the way to go.

But in the end I like the old siloed do-your-stuff way more. It works and gives you actual ownership and freedom. It turns out that it is easier to cooperate when you can say no.
