> Why this matters: Modern infrastructure uses too many execution engines — Docker for dev, containerd for production, Firecracker for isolation, CRI for Kubernetes, MCP agents for AI.

It is my understanding that Docker Engine adds capabilities (such as network stack) on top of Containerd (which is a project maintained by the same people), and "CRI for Kubernetes" is a Container Runtime Interface which COULD be something other than Containerd but often is just Containerd. So in essence the reason why yet another runtime exists is that we have a runtime for containers (Docker/Containerd, Containerd and, for example, Containerd as the CRI in K8s), a runtime for isolation and a runtime for AI agents.

That seems like an unnecessary argument on its own, which makes me wonder why it's listed as the first argument.

Ps: I fear the day keyboards will ship with a "—" button, so we can no longer easily identify AI generated text.
