Well, the view that we can do without "Operating Systems", or rather have the language be the operating system, is not new. It has always been pretty popular in the Lisp, Smalltalk, Forth... communities.
Daniel Ingalls famously wrote in 1981: "An operating system is a collection of things that don't fit into a language. There shouldn't be one." [1] A few years ago a paper argued that Plan 9 was basically trying to achieve that Smalltalk vision. [2]
And if you think about it, that view is extremely fashinable today, with the rise of unikernels [3]. Granted, they are not used for Desktop systems as of now, but who says they won't be in a few years.
