You’re absolutely right that sysadmin jobs moved up to new levels of complexity rather than disappeared. That’s exactly my point.

Kubernetes didn’t democratise operations, it created a new tier of specialists. But what I find interesting is that a lot of that adoption wasn’t driven by necessity. Studies show 60% of hiring managers admit technology trends influence their job postings, whilst 82% of developers believe using trending tech makes them more attractive to employers. This creates a vicious cycle: companies adopt Kubernetes partly because they’re afraid they won’t be able to hire without it, developers learn Kubernetes to stay employable, which reinforces the hiring pressure.

I’ve watched small companies with a few hundred users spin up full K8s clusters when they could run on a handful of VMs. Not because they needed the scale, but because “serious startups use Kubernetes.” Then they spend six months debugging networking instead of shipping features. The abstraction didn’t eliminate expertise, it forced them to learn both Kubernetes and the underlying systems when things inevitably break.

The early 2000s sysadmin managing physical hardware is gone. They’ve been replaced by SREs who need to understand networking, storage, scheduling, plus the Kubernetes control plane, YAML semantics, and operator patterns. We didn’t reduce the expertise required, we added layers on top of it. Which is fine for companies operating at genuine scale, but most of that 95% aren’t Netflix.
