Robert Martin, of XP fame, really hit the nail on the head in this [http://www.butunclebob.com/ArticleS.UncleBob.TheNextBigThing article].
His basic premise is that what the industry needs is more craftsmanship and professionalism, and not another silver bullet to go chasing after.
I may post his last paragraph to my cube wall. Part of it reads:
I hope the next big thing is the growth of professionalism and craftsmanship, and the realization that these are the attributes, not documented process or raw manpower, that will make our industry productive, accurate, and respected.
