I don't agree at all. While the large majority does not need the scalability it offers, it can benefit from all the other stuff applying the 'best practices' offers. The problem is - that many people do not stick to the best practices and do not know how to build containerised applications.

Implementing the whole "DevOps" idea just becomes a whole lot easier when developers don't even have the concept of their snowflake server anymore. And yes - k8s has a ton of overhead and is pretty complex to get into at first, but it all makes sense. There are many points that could be criticised about it, it's far from perfect, but having a standardised way of deploying whatever application has been a massive game changer in the development environments I've been thrown in.

Source/disclaimer: I'm a consultant that has seen quite a few k8s/openshift fuckups and success stories, both on large and small scale.

>I'd argue Kubernetes isn't the best choice for the bottom 90%.

Exactly. Instead of having something so simple that scales for 90% of everyone's needs. We have solution that Most enterprise wants and filter down from top to bottom. And it is true in almost all Tech things related.
