What's unfair? That the arguments made by emacs users with respect to less powerful editors resemble the arguments made by Lisp users with respect to less powerful programming languages?
I'm not taking a stand on the argument one way or the other, just pointing out how similar they sound. You said:
"There are huge benefits available if you give up all your existing editing tools and spend some time (and yeah, it can be months to years) getting really, really good at just one. Really, that one has to be emacs or vim, which are the only editors out there designed to scale to this level of specialization."
How does this differ from:
"There are huge benefits available if you give up all your existing languages and spend some time (and yeah, it can be months to years) getting really, really good at just one. Really, that one has to be Lisp, which is the only language out there designed to scale to this level of specialization."
Whether you agree or disagree with the sentiments, haven't you heard people expressing those sentiments in much the same terms?
