That's funny ... brings back memories of the 90s :)

One thing I've noticed is that in modern IT infrastructure, there is usually two levels of sandboxing going on. At the low level you have VMs (sandboxed OS), and on top of it you have containers (sandboxed applications). Sysbox makes it easy replace that lower level with containers (which naturally leads to docker-in-docker or more accurately containers-in-containers).

To be clear I am not saying that containers are equivalent to VMs or that containers should always replace VMs. They are different beasts with different properties. But I am saying that in many scenarios it does make sense to use containers instead of VMs, particularly if your stack is all Linux, you don't need the isolation strength provided by VMs, and want the higher efficiency of the container.
