Looking at tools like Kubernetes - there aren’t  years and years of incremental updates to the software like you’d find in Windows, Linux or VMware. There’s not a society of professionals who have built their careers on working with the software. The tool is new, and the experience level for those implementing the tool is limited. Additionally, if you look deeper at surveys from this result, you find that more and more of the community implementing the tool is not from a classic IT, but a developer background. The implementation of new tools is only increasing, and the likelihood of having a resource with truly deep expertise is becoming less likely, and often less needed. Kubernetes 1.0 released in July 2015, there are few people on the planet with years of experience with the system.
