This is sort of a strange argument. If your argument is that we need to factor in prior knowledge, naturally I will ask: how MUCH prior knowledge?

* do i need to factor in experience with VMs?

* do i need to factor in OS and networking theory learnt in college?

* do i need to factor in high school algebra?

* do i need to factor in learning the english language?

Of course you need to factor in learning k8s. Before, it was learning VM's+ {ansible, chef, salt}, before that it was prob something else.
