The article gives very clear idea, that "non-functional DNA" can become very functional after transposons spring into action(at birth, during illness, whatever the trigger), so writing it off as something that can be spring cleaned is too early. As for clean house - what exactly is template here? Some humans have genes, that others don't have - DNA is not something, that has all the attributes of all humans with true/false values attached to them. Some humans have slanted eyes and have genes that are responsible for that look and others don't have such genes when they have no such feature and there are other genes responsible for their look. And this looks a sh!t job to sort out all "functional" genes of every human, as DNA of them is not going to be the same. Editing out nonfunctional DNA looks like one of those ideas from 60s, when it was in fashion to remove appendix and make smaller stomach and they in the end paid with shorter lifespan.
