Open source runs the world. That's for supercomputers, where Linux powers all of the top 500 machines in the world, for smartphones, where Android has a global market share of around 75%, and for everything in between, as Wired points out:

When you stream the latest Netflix show, you fire up servers on Amazon Web Services, most of which run on Linux. When an F-16 fighter takes off, three Kubernetes clusters run to keep the jet's software running. When you visit a website, any website, chances are it's run on Node.js. These foundational technologies -- Linux, Kubernetes, Node.js -- and many others that silently permeate our lives have one thing in common: open source.
