K8s absolutely reduced labor. I used to have a sysadmin who ensured all our AMI images were up to date and maintained, and who maintained a mountain of bespoke bash scripts to handle startup, teardown, and upgrade of our backeneds.

Enter K8s in 2017 and life became MUCH easier. I literally have clusters that have been running since then, with the underlying nodes patched and replaced automatically by the cloud vendor. Deployments also "JustWork", are no downtime, and nearly instant. How many sysadmins are needed (on my side) to achieve all of this, zero. Maybe you're thinking of more complex stateful cases like running DBs on K8s, but for the typical app server workload, it's a major win.

Fair point, but I think you’ve actually illustrated my argument perfectly: you didn’t eliminate the need for specialists, you outsourced them to your cloud vendor. Those underlying nodes being “patched and replaced automatically” by AWS/GCP/Azure? That’s their SRE teams doing exactly the work your sysadmin used to do, just at massive scale. The control plane managing your deployments? Cloud vendor specialists built and maintain that.

And I’d wager you’ve still got people on staff doing operational work, they just don’t have “sysadmin” in their title anymore. Someone’s managing your K8s manifests, debugging why pods won’t schedule, fixing networking issues when services can’t communicate, handling secrets management, setting up monitoring and alerting. That work didn’t vanish, it just got rebranded. The “DevOps engineer” or “platform engineer” or “SRE” doing that is performing sysadmin work under a different job title.

Managed K8s can absolutely reduce operational overhead compared to hand-rolling everything. But that’s not democratisation, that’s a combination of outsourcing and rebranding. The expertise is still required, you’ve just shifted who pays for it and what you call the people doing it.
