Sure! So, Kubernetes is Google's attempt to make real, full-strength Google-ish infrastructure "as simple as possible, but no simpler". This kind of infrastructure is really hard, so "as simple as possible" is still quite complicated. This makes k8s a pain in the ass to understand and use.
Docker swarm comes from the opposite end - it's dead simple to use, and seems to be aiming for the 80% use case. After all, most companies are not Google, and can work with a less complicated solution that offers a "Just Push Go" experience. The downside is that it's less flexible and less robust. (I also get the distinct sense that the engineering was rushed. But that can be fixed if it stays popular for long enough - eg I hear MySQL is decent these days.)
The potential problem, as kuschku is pointing out, is that the bigger, more Enterprise-y and more lucrative customers become, the more likely they are to want the power and robustness of Kubernetes. This presents an existential threat to Docker Inc. They could end up fully commoditised, building a vital platform that provides tons of value, but which they can't charge for because all the big support contracts go to Kubernetes Managed Services Providers or whatever.
