Yopu could try, although it is usually not a useful discussion.

There's nothing more natural than an editor analyzing text in a
buffer.  Why it frustrates you is beyond me.

Emacs Lisp is not a general-purpose programming language.  It is a
language for implementing Emacs and Emacs extensions.  Thus, comparing
it with Python is, in general, simply wrong.  We can compare a few
specific aspects, but not the languages as a whole, and definitely not
their success rate: the scope of Emacs Lisp is limited to Emacs, which
is orders of magnitude more narrow than the scope of Python (or any
other general-purpose programming language).
