This is something I have thought about before when it comes to Docker. "It's just a fancy chroot" is what people often say.

While there is some truth to that statement, the real "innovation" is getting millions of people to share and collaborate using the framework. How do make it easy to share and collaborate? Making the technology as frictionless as possible.

I don't see Dockers rise to prominence as a result of some spectacular technical innovation. It's a group of technologies which already existed but now with a great UX around it.
