The one point I keep driving is Kubernetes does so much useful stuff that is a pain to manage otherwise, that it's totally worth the risk currently posed by its rough edges. I'm hoping that came out clear in the article.
Maybe this is the analogy: k8s is now the infra equiv of npm / js frontends, where you need to run to stay in place, and will increase day-to-day strain on everyone. If you're ok with that price b/c your other things are so on fire in a few very specific dev+services at-scale ways, start. Otherwise, give it another X years before you slow down your team(s) & business.
