Would you feel differently if you hadn't already ramped up on all those technologies?

What I mean is that since docker sort of overlaps with much of what people are doing with configuration management, containers, build/packaging systems, and virtualization, it has the potential to reduce the complexity of the stack. If someone's starting fresh, they can potentially avoid having to learn to use and deploy some or all of those different components and just go with docker.
