It's been my experience that nothing in infra and ops will ever "just work". Even something like Heroku will run into scaling issues, and how much you are willing to pay for it.
If people's concerns is that they want a deployment platform that can be easily adopted and used, it's better to understand Kubernetes as the primitives on which the PaaS that people want can be built on top of it.
Having said all that, Rivet looks interesting. I recognize some of the ideas from the BEAM ecosystem. Some of the appeal to me has less to do with deploying at scale, and more to do with resiliency and local-first.
