What if instead they revamped their ancient microservices into modern monolithic applications?

I'm sorry, but I can't stand this kind of bullshit. You cannot possibly take two random things, put 'modern' in front of one word and 'ancient' in front of another, to justify changing things.

The problem of Kubernetes is probably that people started drinking the microservices koolaid and now need complex solution to deploy their software that became more complex when they adopted a microservices architecture.
