Kubernetes is probably more responsible for deskilling, or at least constraining, the expertise, of SRE/devops/platform/infrastructure engineers than anything.

I don't think that's a bad thing, it makes infrastructure more consistent and less weird (assuming you understand k8s) but it is a very high level of abstraction and for a bunch of people is just a black box.

Continuing the never ending trend of Sys Admins/DevOps/SRE job title holders with skills in specific tools rather than foundational skills always wondering why they are out of a job every 5 years.
