>You are just stating it. Without any reason. One can't argue against a statement, you have to provide reasons behind your statement for there to be an argument.

Not really - he already gave both. The argument is the already stated one "Emacs is not the solution to the problem of people coming to Lisp needing a good programming environment". And the reasons are what he wrote above: "because there are millions of developers that won't use it".

Now you might agree or not with the latter (I for one am in the category that wont bother to use Emacs), but it's a full argument.

>I've never heard people say 'it is unreasonable to ask people to use Android Studio to develop for Android'

People still say that, but that's beside the point.

Android Studio is a typical modern IDE, so not much of a barrier to entry. Emacs are much more arcane and idiosyncratic (and doubly so outside the Unix world, e.g. for the huge majority of Windows and OSX based devs).
