"Repeatability is great, but who doesn't have that already?" Almost everyone. I think this is the heart of the misunderstanding right there. 99% of developers don't have access to a repeatable deployment system. When they do, it severy limits what they can deploy, and where. You mention in your article that the "secret sauce" of docker is "not that clever". The point is not to be clever but to solve a problem. The fundamental technology for solving repeatable deployment has been available for years, and what do those in the know have to show for it? We're all still reinventing the wheel for every single damn project, wasting huge amounts of energy in the process.
