It's tricky because you almost never truly work on sophisticated systems as a whole. You usually interact with a small part of them that tends to be meaningless, (e.g. writing YAML files for complex k8s). The exception to this would be if you are the one designing the system, but then most sophisticated systems tend to grow from necessity rather than central planning. That's my experience at least.
