Kubernetes does simplify and abstract - just like C++ simplifies and abstracts compared to writing assembly. :) In both cases, the scope of what you can do expands significantly, which means that the systems you build with the higher-level tool are significantly more complex, which means that you see much more confusing C++ programs and Kubernetes deployments than assembly programs and five-lovingly-handcrafted-servers deployments.... but that's because you can successfully start with a more complex idea and make it happen.
