Completely agree. The thing is that the problem it's designed to solve has been badly misrepresented.

If your problem is "At Google, we have fleets of thousands of machines that need to cooperate to run the world's busiest web properties, and we need to allow our teams of thousands of world-class computer scientists and luminaries to deploy any payload to the system on-demand and have it run on the network", then something like Kubernetes might be a reasonable amount of complexity to introduce.

If your problem is "I need to expose my node.js app to the internet and serve our 500 customers", it's really, really not.

And it's probably used by many people who don't know how to optimize a query, so they go for big data clustered solution instead.
