Good points but I think it would be accurate to say that Docker solved a developer problem. But developers are only part of the story. Does Kubernetes solve the business' problem? The user's problem? The problems of sys admins, testers, and security people? In my experience it doesn't (though I wouldn't count my experience as definitive).
At my company we have had better success with micro-services on AWS Lambda. It has vastly less overhead than Kubernetes and it has made the tasks of the developers and non-developers easier. "Lock-in" is unavoidable in software. In our risk calculation, being locked into AWS is preferable than being locked into Kubernetes. YMMV.
