K8s ruffles my feathers because it’s entirely too easy to build on it (without proper IaC, natch) without having any clue how it works, let alone the underlying OS that’s mostly abstracted away. /r/kubernetes is more or less “how do I do <basic thing I could have read docs for>.”

I’m a fan of graduated difficulty. Having complex, powerful systems should require that you understand them, else when they break – and they will, because they’re computers – you’ll be utterly lost.
