Docker is not just containers, but image/container fs management is a key element too. Union fs with copy-on-write makes a big difference against traditional containers. And the image ecosystem, the easy creation with dockerfiles and a good api/powerful cmdline command are pretty important elements too.
Other containers technologies could learn/adapt that other docker ideas, and even VMs could get a bit closer to them. No matter if Docker is the dominant implementation there in the future or not, with those core ideas we all will win.
