JavaScript and the module ecosystem around node have created a culture of building. It wasn't long ago that we stopped building, and were just configuring. Need a webserver, configure apache. Need a database, configure mysql. Today we don't hesitate to build web servers, proxies, and even databases using the module ecosystem.
Enter: Runtime.JS, an operating system kernel built on V8 JavaScript Engine.
If we have our metal layer, the hardware layer, instead of Linux, we're going to run Runtime.JS. Runtime talks directly to the hardware, to the X86. And on top of that, we have JavaScript. There's no file systems, networking layer, or things you normally deal with when it comes to computer systems.
