The conflation of containers and K8s is pretty damning. I personally believe k8s is an early realization of orchestration and will be superseded by better ones. Building yet another orchestration system is a cottage industry at the moment and I've noticed that the existence of k8s hasn't impeded it.
And "spin up a linux box" is deeply naive. It is the habit of spinning up linux instances that leave companies and other institutions with huge collections of neglected, mis-configured, vulnerable linux VMs spread all over the planet with 0.1% average utilization.
Developers popularized containers, independent of the cloud or the troubles of operations. Containers solve tough development and packaging problems and have value whether the ultimate deployment abstraction is 'docker' or some microVM system. The most likely use case for whatever microVM product one might imagine is running containers.
* As for microvms running containers -- in this case Nanos doesn't run Linux so it can't run containers.
I find it very irritating and deceptive that the author wildly equivocates between containers and Kubernetes almost every sentence. And it's incredibly condescending that they suggest people buying the container Kool-Aid are simply too young to have done development and operations on regular servers/VMs, "duh!" Or that they're just trying to pad their resumes. No, I've had plenty of years of experience doing that, and I find containers far simpler to develop with, deploy, maintain, and update. And I've never used Kubernetes.
As most others have said, this comes across as extremely patronizing and demeaning marketing FUD from a company so certain that they're obviously right and almost everyone else is mind-numbingly wrong that even if that's actually the case, no one is ever going to believe them; and very justifiably. This is not how you do marketing, or write prose or communicate in general.
