I completely agree with these views, and that's one of the reasons I use
Emacs.  But Eli said:

   If this tendency continues, we will soon lose the ability to make
   deep infrastructure changes, i.e. will be unable to add new features
   that need non-trivial changes on the C level.

Solving problems in C is useful for "deep infrastructure changes", like
xwidget, dynload/modules, bidi, lexical scoping, GnuTLS support, font
rendering, Emacs server etc.
