Ha, I can at least assure you we're not oblivious. Nomad has a product manager from Mesosphere and most of HashiCorp's products integrate deeply with Kubernetes. We're well aware Kubernetes is the juggernaut to which every other scheduler has succumbed.
I believe there's room for both Nomad and Kubernetes. Whether as competitors or complements, having more than one vibrant project in the orchestration space will hopefully make all the projects better for users. Any one project has to make tradeoffs that improve the user experience for some while degrading it for others. For example Kubernetes has an IP-per-Pod network abstraction which provides an excellent out of the box PaaS-like experience for microservices in the cloud. On the other hand Nomad's more flexible network model more easily supports networks outside of flat cloud topologies whether it's small home raspberrypi clusters or globally distributed edge compute.
