Ask HN: What's Next After Kubernetes?

For a while now, I've been asking myself this question because it seems a lot of intermediate solutions get drowned out by all the k8s-related news.

I was encouraged to see the announcement about mrsk from 37Signals which may be part of a growing minority of folks who reject the complexity of k8s.

I also remember reading an article in which some of the original k8s authors described how they might change things knowing what they know now. If someone has a link, please share it.

So will there be a Kubernetes v2 or will there be some other big thing that still checks a lot of boxes but doesn't necessarily involve the complexity?
