there is a reverse relationship between education/access to information and adherence to beliefs that are contrary to science, logic and reason. It may take many decades, but the hand writing is on the wall for all high-control cults and denominations of mainline religions. Either get real or go under. The present attraction to literalist dogmatic religious orgainizaitons, from Islam to Christianity is fueled by the desire for instant gratification, simple answers and quick fixes. Things don't work that way in the real world.
With the rapid industrialization of the rest of the planet and access to the web, I'd give the JW cult thirty to forty years before it is a footnote on the pages of religious annals.
