Earlier quoted context omitted.
I think you're making the case for language irrelevance even more. The reason big corp. can't move fast isn't because of their technology choices. It is because of all the bloatware and bureaucracy. You can be bureaucratic and bloated in any language.
But in some languages bloat is a best practice.
Let's say you're talking about Java. A "bad" team will have mountains of code. A "good" team will apply Greenspun's Tenth Rule and use a lisp to compress down the mountain to the extent that "lisp" can compress it over Java.
You may protest that the lisp has angle brackets and that it's inferior to say Clojure, but the machine does not care.
