Software engineering seems to be ridden with hypes: someone launches a "new" idea, a lot of noise is made over that in the various journals which leads the casual reader or listener to believe that all previous ideas are very wrong or at least completely ancient and therefore useless. The new idea inspires the creation or resurrection of a bunch of TLAs and FLAs and other buzzwords. But after a while the hype is gone and the new idea is either forgotten or becomes an old and more or less well-understood tool - one of many and not one instead of many.
