The learning curve for docker is minimal. As I mentioned before it's very useful in CI systems where you want to be building and testing your code in a clean environment that is reproducible across machines. Trying to debug when a core library or header dependency is missing to build your code requires far more skills and differ between operating systems and versions of operating systems. The problem isn't moved upstream, it's tackled in a very clever and well packaged manner.
