I think a lot of people are gradually realising (althought not admiting to themselves) that the 1914 jig is up.
I'm hearing these type of comments from my uber organisation loyal pioneer 'friends' re the generation change:
"I'm not serving with a date in mind anyway", and "Even if it's wrong, it's still the best way to live".
There's a tactit acceptance that the overlapping generation theory is a bunch of crap, and at this point I think it would be a relief to the 20-40 something JWs if the society would can the 1914 doctrine entirely. To be honest I don't know why they don't, the older generation of JWs are too invested in the religion, and too depressed about the end not being here to leave anyway.
By older generation, I am of course, using the actual meaning of the word generation.
