I would argue that Sun's innovative output was a much larger missed opportunity than anything Docker has developed (then again, hindsight is 20-20). Yes, Docker has a lot of hype and has "brought containers to the masses" but I would argue it's nowhere near as revolutionary as ZFS/Zones/DTrace/etc. If I had been born 10-15 years earlier, I would've hoped to work for Sun. I've never wished to work for Docker.

As someone who maintains the container runtime underlying Docker (and contributes all over the stack), in my view there is a lot more innovative "core" engineering happening in the LXC/LXD camp than in the Docker camp. There are far more kernel patches coming out of LXC (and more kernel maintainers developing LXC) than have come out of Docker. And let's not forget, LXC came first to modern Linux containers. There is a lot of work going into Docker, but I guess I put more of an emphasis on OS engineering to determine who more innovative engineering on systems tools.

(Yes, there is Kubernetes but that's not a Docker project. If anything, Swarm emphasises my point. LXD has clustering too and they support real live migration between cluster nodes -- though CRIU has historically been a bit hairy.)
