Related to what James Woods said, it really shows why there is no point in wasting your life trying to "bring down the org" and the like. A failed date prophecy like 75 is the worst case scenario. Yet negative growth only hit 1 or 2% in the years after. Then in the early 80s, it churned ahead at 3-5% for years. WTF?
Yes the internet is a game changer, but it will take decades as the old guard dies off and the new generation to fully discount the religion as total bullshit. In the meantime, the org as a whole will chug along in one form or another for another century at least. We aren't going to outlive it!
If you are "in" and lurking, get out ASAP. Don't sit around waiting for reform. If you are trying to get your family out, set a firm timeline, but if you can't get them out, get out yourself. You only get one life to live, wasting those precious hours in the KH will only drive you to insanity.
