Re: A Ubiquitous Weapon for Mass Distraction and Destruction and Disruptive Creation?

The concept of what an OS is has been rather fluid ever since virtualisation raised its head on mainframes. If you run Windows as a virtual OS on BSD or Linux on Windows - or these days just running WSL as part of Windows - what's the OS as far as the application is concerned. We're dealing with layers and all the application can do is take whatever provides its API is the OS. For an application running in a browser that's the browser. If you want to look as far as the hardware* then the OS is the entire stack up to and including the browser but all the application sees is the browser.

* Given that the processor's instruction set is apt to be an artefact provided by microcode what actually is the hardware as afar as the OS is concerned?
