The problem with your argument is that, it ignores that fact that a
person will come to value high integrity software only by using a
language the supports the paradigm.

There has to be interaction and feedback.  Many programmers (say, using
C) are oblivious, because they don't get that feedback from their
language.  What the Ada guys know just seems like theoretical
gobbledygook to them.

Here are a couple of books about cybernetic theory and constructivist
