You don't think it requires some expensive mainframe admins, even with the fancy software? Anywhere I worked with a mainframe, the mainframe admin was highly distinguished within the org and extremely knowledgeable.

I would argue Kubernetes talent is cheaper than mainframe talent these days because it's ubiquitous.

I think the rough premise is there's a 1:>3-5 ratio of "super knowledgeable mainframe guy" to "super knowledgeable kubernetes guy".

Also, Kubernetes talent is far from ubiquitous. That sounds more to me like you're counting anyone who has successfully deployed one time.

Yeah, I am that super knowledgeable K8s guy, but I’d still say true mainframe admins are still a higher metric.

But in regards to K8s talent, lots of the people who think they know Kubernetes in production but have never had to actually upgrade the cluster, or go through the process of having to update manifests, deployments, and CSIs, and having to actually deal with api removals.

Agreed. The tooling around upgrades is painfully atrocious, and stuff like kubepug [1] should be part of the Kubernetes core.
