It was a fancy lie about their spare time, but especially in dotcom, there IS no spare time to learn architecture.
What I’ve seen of dev AND ops is that their knowledge is focused well on their own things. And when it comes to the other half of devops they just want the shortest path back to doing their thing. This has caused absolute princess devs to be nearly screaming about the hassle of security and change control and infrastructure and proper code deployment and testing and … Well, a lot of things.
It doesn’t pay to have people learning to half-ass dev because ops is your thing. You need advocacy on both sides of that line, still.
