The real shift Kubernetes made was from infrastructure as code to infrastructure as data: you declare the object and control loops reconcile it, instead of running a program.

we went from infrastructure is code to infrastructure is data and infrastructure is code is like if this do that um bring in this module for loops all this stuff and Kubernetes is like no no no you have to specify exactly the containers you want how much memory that they need and then we have the status field to tell you if they were running or not
