I think it's interesting more in the sense of understanding what Unix is today. It doesn't really read as an argument against a Plan9-like realization of everything-is-a-file. I'd summarize those posts in two main points: 1) Linux isn't a research project. 2) Bringing a Plan 9-like realization of everything-is-a-file into modern Unix really just creates an even uglier chimera than Unix already is.
