There seem to be two issues raised in your post. One, whether there is a
connection between the discussion of technology and critique of
functionalist language. This seems to be an easy yes. Heidegger's
critique of modern language theories is that they are merely technical.
Thus the shortcomings of a merely technical understanding of technology
also apply to the technical understanding of language.
The second, albeit related, point is whether Heidegger's writing style
takes account of the very critique he raises, i.e., whether his writing
becomes "poetic". This is trickier. Certainly his later writings are
different than his works around the time of Being and Time, which are
characterized by a technically adroit precision of language, laying out of
terms, defining, and the like. In other words, the methods of logical
positivism applied to a phenomenon resistant to these methods. One could
see his later style as a means to address this disjunction inherent in
Being and Time.
Two factors complicate such a "progressive" development. One is whether
another poetic language is really possible. The second is whether
Heidegger really uses it, or rather retains a distinction between poetry
and philosophy. While Heidegger maintained that another language was
possible, his own writing style is not poetic, in the sense of which you
use the term ("constructing realities"), but thoughtful. (Heidegger can
grind down the distinction between poetry and thinking only by making them
both responsive to Being, which makes poetry no longer a making or
creating.) Thoughtful thinking slowly circles around essential words, to
pick apart and uncover the varieties of meaning, discover forgotten
meanings, and chart genealogical connections among the changes. The best
example is "The Principle of Reason," in which Heidegger continually works
on Leibniz's little principle for about 200 pages, a Holzweg pattern to
reading, checking out paths that often turn into dead ends, but it is
undertaking the path itself that is important. By Heidegger's own
insistence, this way-taking is preparatory thinking: it is not poetic
thinking itself. Nonetheless, this form of thinking is not technical in
the sense in which he uses the term.
