My pet theory is that open source is very much about packaging things. I remember being amazed when I discovered that there was this a system, called GNU/Linux, where everything you need was already packaged and easy to install. Then came the Maven, npm & co. Docker (and containers) is basically an universal package manager that was fulled by the success of open source, the arrival of a lot of new people (working on Mac and Windows) in that space and the adoption of the cloud. Docker Hub became the open source "app store". The crime is the misleading term "container" because I bet a majority of people assume there is some security guarantee by design, what is absolutely false. Actually container security is pretty hard and a most people don't really care because it doesn't run on their computer but in the cloud. My guess is something like Kata containers, compatible with the container standards while leveraging hardware virtualization technology will prevail. Or a cleaner system, similar to NixOS/Guix but easier to use, will appear.
