The nature of clickbait titles is that they instill a misleadingly false, exaggerated, or ambiguous narrative that is not matched by the content. This title is ambiguous, and has lead many of us on with the more enticing (controversial) narrative that containerization is dead. It doesn't matter what is in the content.
Docker as a software product may die pretty soon as people switch to containerd which includes more or less all the functionality you want and none of the bugs you don't want.
If you use Docker post version 1.11 (like many people do) you already use containerd (and runC)

Despite the rise of Kubernetes, it's not for every use case and far from it. Docker Swarm and Docker Compose are extremely valuable with small deployments and development. It's by the far the easiest and simplest way to get a cluster up and running.
That said, with all major cloud providers now offering Kubernetes cluster management with a free Kubernetes host, and the economy-of-scale offered by those cloud providers driving the costs of cloud computing down, I'm not sure how Docker Swarm can compete.
