The argument stretches “Unix philosophy” so far that Lisp systems end up being a better fit for it than Unix itself. To me that just makes the whole thing lose meaning. Emacs doesn’t particularly fit the Unix philosophy and that’s fine!

Thanks for reading my article, and for your thoughtful comment!

I will go further and say that no GUI or TUI application fits into the Unix philosophy.

I suppose I can agree with you on this point for sure, since the Unix philosophy is not really all that well formulated to begin with (it is a philosophy closely related to the principles of functional programming devised by people who were seemingly not interested in functional programming).

Nonetheless there are people who still insist there is wisdom in the Unix philosophy, which I think is more misguided ritual than carefully-considered principle. The reason I wrote the article was to make people question the utility of this ritual, of drawing an arbitrary border line around a piece of software and saying "within these borders is a tool that does just one thing and does it well."
