One thing I noticed about whole SRE/devops scene lately is that there seems to be no grasp of the KISS principle, there are people building elaborate glass houses on top of k8s (tho k8s+pipelines is very useful its easy to get carried away)
another observation is that the people who are not good programmers but are good at appearing to get stuff done (but who create tons of tech debt) seem to fall naturally into SRE roles, as there is no testing culture in pipeline driven development
SRE currently is like the wild west, it be many years before it starts to resemble engineering
