Blondie, I remember hearing that same statement. Along those lines we were told that it would be much too confusing for those who lived centuries ago to suddenly be thrust into the world with electricity, airplanes and automobiles. Yet I never saw those things in wt renderings of "paradise" so that didn't make sense.
Sometimes I think they have new ideas in a few talks to see if they stick. If not, you don't hear them again, they just try something else that doesn't raise so many questions.
