In principle, this could be a four-word essay because the short answer is, "no, of course not!" Indeed, my asking the question entails a slight personal risk: I certainly don't want to alienate my friends who are numerical analysts. I've worked happily, if not exactly in, then certainly someplace near the field of numerical analysis for many years. I've even taught it (not a guarantee against being boring, I know) and coauthored a book on one of the field's many active subareas.
