Back in the late 90's when internet discussion forums started getting popular and even through the heyday of this forum in the early 2000's, I think many people felt there was gonna be some big moment when it was all exposed and people en masse would see it for what it was and we'd hug and make up with our jerk relatives and they'd say "i'm sorry, i was wrong".
Not gonna happen.
It's gonna be a slow fade into an internet version of TBN. (for non americans, that was a corny religious variety show that may or may not still be on).
Eventually a century from now, they won't even be growing from reproducing, but someone or some group will own the buildings. Some now unborn group of people will close the doors the last time, sell the assets, make a little windfall, and the WT will pass into history. Maybe remembered by future religious studies Phd candidates writing a thesis on obscure american religion in the 19th century.
