bigmac - I've often thought about that myself. I'm thinking in about 20 years the bulk of the pre-information age folks will have died off and many will realize that they never "made the truth their own" at that point. plus this will coincide with the failure of the overlapping generation time limit, so I can see this being a huge drop off point for the cult. If they see it coming, I suspect they'll push 2034 as the date for armageddon, but that will fail and many will leave.
I can't wait that long, though...
